#Dungeon23 – Week 3

Each week I will be posting my progress in creating the dungeon, NPCs, lore, and the surrounding area. My version of #Dungeon23 is to make progress every day. Most days that will mean a room description or using a dice drop to generate a section of the dungeon. Other days will include adding lore, NPC, and other descriptions needed to fill out the document to my satisfaction. The blog post each week will be a copy-and-paste directly from my personal google doc. My hope is to show how this dungeon and area evolves over the year.

Change Log. changed wandering monsters; filled out rooms 12 and 13; hallways H1, H2, and H3; info on creature tribes; two dice drop sections to add on to floor 2

Previous Entries. Week 1. Week 2.

Deep in the Kyusoku Mesa hides the ancient vault of ‘Vaelving Gamles’ which holds a fabled warhammer with the power to unite the local tribes. A deep scar carves a wedge into the middle of the mesa. A lush jungle covers the scar and other portions of the mesa. The rest is an unforgiving desert. The tribes of the Resu’suteppu have called this area home for centuries.

The ancient vault was built centuries ago by the local stone giants to protect (and hide) their most sacred possessions. Long after the giants abandoned the vault local tribes of elves used parts of the upper floors as emergency shelter in times of need. Most recently it has been the focus of a foreign War Priest (with claims of local blood) to find the fabled warhammer Endbringer, and unite, and rule, the tribes of the mesa once and for all. 

Hook: A retired general is hiring adventurers to map the halls of Vaelving Gamles.

Hook: A foreign War Priest is paying anyone who brings them magic items from the depths of the vault.

The town of Unrock provides many accommodations for the locals and the many adventurers that pass through the region.

Topside provides more goods and services to the area and is more affluent than Unrock.

General Features

The vault of Vaelving Gamles is made up of a combination of smooth, worked stone and hand-hewn stone, with the occasional natural tunnel or cavern. Some areas have exceptional architectural features that are noted in the text.

Ceilings. Built to accommodate many types of giants, the room ceilings are at least 35 feet at the least and as high as 50 feet in the more important spaces. Ceilings in hallways are approximately 40 feet in height. 

Doors. Locked wooden doors require a successful DC 20 Dexterity check with thieves’ tools or a key found on the same floor. Large stone doors require a successful DC 15 Strength (Athletics) check.

Light. Large sconces can be found in most rooms and hallways. Whether they are lit is another question.

The Giant Archway, Vkhod Arku, Floor 1

Wandering Monsters. Check for wandering monsters if the players move to a new area, make a lot of noise, spend too much time in one area, or at the dungeon master’s discretion. Also, an encounter can occur at the dungeon master’s discretion without a roll. Check for wandering monsters by rolling a d20. On a roll of 17-20, an encounter takes place. Roll a d6 and consult the wandering monsters table. On a 20, roll twice on the table and use both results.

11d4 + 2 Giant Rats
21 d4 + 2 Giant Centipedes
31d4 + 2 Skeletons
42d4 Goblins
51d6 Kobolds
61 Grey Ooze
Wandering Monsters Table Floors 1 & 2

Giant Rats. An oily smell precedes the sight of rats gnawing on bat carcasses.

Giant Centipedes. The skittering of hundreds of legs on the floor approaches slowly out of the darkness.

Skeletons. Undead skeletons can be found repeating echoes of ancient actions of their past lives like standing guard, patrolling a hallway, or playing cards. The dark energy that animates their bones compels them to attack any living creatures on sight.

Troglodytes. A group of troglodytes is scouting the vault for a possible new lair.

Swarm of Bats. Screeches pierce the air as a group of bats erupt from the darkness above flying around chaotically.

Gray Ooze. Blending in with the stonework, the gray ooze waits for the perfect moment to strike unsuspecting adventurers.

  1. The Vkhod Arku

A giant archway built into the mesa holds an alcove that nature re-claimed long ago. Faded murals dedicated to the giant god Annam All-Father. Small scripts in ancient elvish provide directions beyond the stone doors. Two giant-sized stone doors require a successful DC 13 Strength (Athletics) check to open. There is a chance this room is occupied. 1d6: 1d4 kobolds and 1 giant goat; 1d4 kobolds; 1 giant goat; nothing; Spy, Priest, Knight fighting 1d4 kobolds; Spy, Priest, Knight resting after a bad fight.

2. Armory

Rotten wood, cobwebs, and rusted weapons lie scattered around. More elven writing marks the two doors. The south corner of the room ceiling has collapsed causing the floor to rise to a ledge in the corner. In the north corner, Goblins and Kobolds are fighting each other over some treasure. In the south corner of the room, a Goblin Boss and a couple Goblins are harrying an adventurer perched on the ledge protecting a large chest. The Scout cries for help as soon as they see the characters. Treasure. 210 sp, 80 gp, black velvet mask, gold vestments, potion of climbing, dust of dryness, and a key to the stairwell in room 4.

3. Antechamber

The floor is partially collapsed in the southeast corner. Several Kobolds are attempting to dig through to access a room 4 floors below. They rigged an old well to be a hidden pit trap that fills with poisoned water over 1 minute. A successful DC 15 Wisdom (Perception) check discerns an absence of foot traffic over the section of the floor that forms the pit’s cover.

4. Main Stairwell

This main stairwell room was originally used as a staging area for going deeper into the vault. Touching any of the small doors causes the character to take 1d10 poison damage and must succeed on a DC 15 Constitution saving throw or be poisoned for 1 hour. There is a chance this room is occupied. 1d6: goblins, empty, kobolds, empty, adventurers, empty. 

5. Guard Room

The heavy stone door is slightly ajar. Once used as a base for the guards of the vault now the room serves as a camp for adventurers. Written on the wall are instructions on how to seal the room from the inside for safety. An almost empty wooden cask holds travel rations and waterskins. Attached inside is a parchment with dates written on it indicating when the rations were last restocked.

6. Empty Vault

The secret door to this chamber was found long ago and was fully pillaged shortly after. All that remains are scraps of broken storage and furniture that have been used here over the centuries. There is a chance that the room is occupied. 1d6: goblins, empty, empty, empty, empty, kobolds.

7. Fake Barracks

This chamber is set up like a small barracks but is a trap to thwart intruders. As soon as the characters enter the room scything blades emerge from the ceiling and walls. DC 11 to detect the trap and the same DC to disable the trap via a panel in the doorway. Each creature in the doorway must make a DC 11 Dexterity saving throw, taking 5 (1d10) slashing damage on a failed save, or half as much damage on a successful one. A mimic disguises itself as a fancy door with no traps. The room guards a chest  containing a bag of gems (tiger eye, 2 rhodochrosite, 3 moss agate, malachite, lapis lazuli, 3 hematite, and azurite), a scroll of greater restoration, a scroll of protection (undead), and a potion of frost giant strength.

H1. Gas Trap Hallway

The hallway between rooms 6 and 7 contains a poison gas trap. When triggered small holes appear in the walls hissing out a purple noxious gas and causing the area to be lightly obscured. DC 13 to detect the trap and the same DC to disable the trap via a panel in the floor. Each creature in the area must make a DC 13 Constitution saving throw, taking 3 (1d6) poison damage on a failed save, or half as much damage on a successful one.

8. Cistern

Many kobolds and a couple goblins fight over the water contained in the cistern. The kobolds are looking for the goblin who sabotaged their water supply. The goblins are fleeing a bad situation with their tribe. Part of the ceiling has collapsed creating partial cover and difficult terrain. A secret door in the southwest corner reveals a secret staircase that goes up and down one floor each.

9. Audience Chamber

Three tiers separate this room. Some furniture still lingers in the far east corner where a historical text can be found in an unknown language (ancient giant). A secret door in the far west corner leads to a hidden hallway. A rotten skeleton can be found in the secret hallway with 6 gp, a dead mouse, a page torn from a spellbook, and a ring of iron keys.

10. Goblin Museum

What was once a torture chamber in ages past has been turned into a gallery for some of the goblin clans’ prized possessions. Ancient slabs of stone are now pillars for trinkets. 1d4 + 1 Goblins are making simple repairs to some furniture and cleaning up after a scuffle with some kobolds. The goblins are willing to help the PCs in exchange for wealth of any kind. Among the items on the pillars are a small mirror set in a painted frame, a giant gold locket, a silver pitcher, a black velvet mask, a potion of animal friendship, and a potion of greater healing.

11. Goblin Game Room

The Goblins turned this old barracks into a game room. Broken wood, scraps of fabric, and a makeshift toy ball lay scattered about amongst odd markings on the floor and walls. A fancy painting depicts a small black line emanating a shaded blend of reds, oranges, and yellows. When touched a wall of force is created splitting the room in half. Any attacks made by magic weapons bounce off and cause 1d6 force damage on the wielder. Normal weapons and physical attacks do damage as normal. The force wall disappears after it takes 10 total damage.

12. Goblin Campsite

An old guardroom has been turned into a campsite and training room for the defenders of the goblin clan. A large patch of green slime clings to the ceiling above a raised platform guarding an enchanted treasure chest. Inside the chest is 15 cp, about 450 gp in gemstones, and a seamless rectangular obsidian box. The only way to open the box is to ask it nicely to open. Any attempt to damage it destroys the contents. The obsidian box contains a potion of animal friendship, a potion of poison, and a potion of greater healing.

13. Ritual Chamber

The magic circle used for rituals can still be seen etched into the floor. Ancient basreliefs depict giants fighting enormous beasts. The north section of the room contains a variety of glass humanoids in several poses. A greater restoration spell or equivalent reverses the glass curse. Using the magic circle triggers a wild magic surge. A group of Kobolds are trying to help one of their friends stuck in a paralyzing mushroom field in the southeast corner of the room.

H2. Collapsed Hallway

The entrance to room 8 has a 1 in 6 chance in being blocked by a collapsed ceiling.

H3. Vaelving Chasm

This hallway features a chasm approximately 20ft wide and 80ft deep. The rooms below are in view and accessible.



Spy, Priest, Knight

Adventuring group that can be found from time to time in the vault or general area. 


Adventurer lost from her party.

The Stonewalker Goblins

This tribe of goblins has been living in the ancient vault for generations. They call the sprawling vaults their home and most of them have never been outside. The kobolds that have recently moved in have been causing havoc to the supplies and resources of the tribe.

Skrax the Goblin King is looking to end the fighting with the kobolds soon so he can go back to breeding his prized hunting rats.

1d8 Goblin Names. Biks, Jorg, Leechbrain, Gnatface, Jhibi, Igugg, Mudleg, Belch. 

The Sharpsnout Kobolds

In the past few months one of the kobold leaders has led them into the depths of the vault in search of ancient artifacts. They tell the kobolds not of what they seek but just to bring them anything they believe is valuable and shiny. Deadly encounters with the goblins have caused some dissent among some of the tribe.

 A young sapphire dragon called Jharthanach is using them to begin building their hoard that’s located in another section of the giant vault.

1d8 Kobold Names. Kirg, Kloh, Erla, Then, Scuz, Trig, Chroma, Tema.

The Broken Crown Troglodytes

Having been chased out of their home this group of troglodytes is looking for a new lair. Their name comes from the obsidian and ruby broken crown worn by the patriarch, Zarm. The trogs have knowledge of the evil that lurks below due to the years they lived there. The trogs also want to find out why more adventurers have shown up in recent months.

1d6 Troflodyte Names. Silk, Skriss, Koldar, Grist, Lid, L’gronk
