Open table experiment in the Caverns of Thracia

Inspired by posts made over on thealexandrian on running an open table megadungeon, I decided to run one myself. Starting with the Caverns of Thracia, I have played 6 sessions so far across various groups. It's a great way to play some more relaxed games (as another game I am currently running is very intrigue heavy, and sometimes I just want to do some dungeon delving).

I did write up the summary of the first delve on another site and was planning on writing up summaries of the others, but I have fallen somewhat behind. Hopefully by starting this blog will help with the focus.

What follows below is the write up I made for the first delve, with some modifications as saying "now" when the delve was last month seems a bit odd!

Armed with a key, random tables galore, and redrawn maps (complete with dynamic lighting on roll20 for that dingy dungeon feel), I informed my d&d friends and organised a game. I have decided to keep a log of the various delves we go on, and perhaps I’ll go into more detail of some more behind the screen stuff too. But for now, the tale of our first delve into the Caverns of Thracia.

Delve 1

For the first expedition to the caverns, we had a party of three brave souls; Athoz the leonin fighter, Iados the aasimar monk, and the warlock Nieven (starting at 2nd level). Before leaving, they rolled up for rumours, with Athoz learning of bat nests in the caverns, so best keep light down not to startle them. He was also told to keep an eye out for strange flora, and an ear out as a strange and loud roar that was heard coming from the caves a few days ago. Iodas learnt that someone who called themselves “the Minotaur King” was leading the beastfolk, and minotaurs are occasionally seen amongst the ranks of lizardfolk and gnolls. They shared their rumours opening, and were ready to go exploring.


Reaching a large stone foundation where a temple or building complex once stood, they found a clay tablet written in a strange language. Unable to decipher it, they descended the wide steps into the caverns. They went without a light, which proved useful as they walked past the huge array of bats living in the starting rooms without disturbing them too much.

The wide entrance room had two exits, right and forward (a left passageway was blocked by a cave in). They went forward, careful not to slip on the inches of bat guano that had accumulated over time. They entered a pillared corridor, again full of bats, noticing a shattered statue at the far end as well as a fissure in the western wall. The fissure opened up to a cavern below, past the reach of their darkvision. As they were debating what to do to try and estimate the depth, Athoz and Iodas heard murmuring to the north; by the statue were a pair of doors, one spiked shut, the other one apparently with someone behind. Iodas listened carefully. While he couldn’t understand the language, they seemed cautious and were debating what to do next. They also sounded reptilian, meaning they were perhaps lizardfolk or similar.

Meanwhile, Athoz and Nieven removed the spike from the other door and had a look inside. It was a nest of large red centipedes, writhing around angry and hungry (4 swarms of insects to be precise, nothing to sneeze at for some level 2’s). Athoz debated spiking the door shut, but Nieven wanted a fight, so combat broke out. A casting of bonfire in the doorway kept the centipedes at bay as they released a volley of missiles into the horde, though eventually some braved the flames to reach food. Athoz was hit with a critical hit, taking 22 damage, his exact health (8d4 is a lot!).

As Iodas dragged away the fighter and restored him with magic (they are sun soul monk I believe), Nieven blasted away with an eldritch blast. The centipedes were emboldened by their success, and they braved the flames to flood the party. However a cone of fire from burning hands killed enough to send the survivors scattering. Those who could not escape into the fissure were finished off in the nest. And with that the room was cleared.

Meanwhile, the occupants of the other room were holding firm (a reaction roll came up as “passive”, so they were waiting to see what happened). They decided to search the nest and get out, rest up, and return later. Prodding through the nest dug up some trinkets; a brass flute, a box with a pair of copper figurines inside, and some sort of arcane stamp or symbol. Not much, but something. Spiking the other door shut, they left.


They rested for an hour outside, Athoz restoring his hit points and Nieven his spells. Iodas had a look at the other ruined buildings, well their foundations at least, and spotted a more intact structure off in the distance, some 60 or so feet from the main stairs. Investigating, it was a low stone building sealed with a thick wooden door, barred with bronze. The party convened to assess the door. No one had thieves’ tools and the lock was far too complex to dislodge with a claw or dagger. So they battered it down with crowbar and maul, and opened up a narrow staircase that led down.


The corridor was narrow, 5 feet to be precise, so they were forced into a single line. At a turn they could see that the corridor seemed to open up into a cave, though there was no floor as they seemed to be at the top end of it. Instead, a rope bridge led across to the rest of the corridor, where they could see a light and a guard, standing there in hoplite-like amour (toughened linen breastplate, spear, shield…). They called out, asking the party to state their business, and didn’t seem too amused at their response of adventurers/explorers. He called for reinforcement, and behind him a door opened up, revealing two more soldiers as well as two robed figures. As the party dithered on what to do (no one wanted to cross the rope bridge), the guard prepared to huck a javelin, though was halted by a robed man who called out to the party.

The man looked cleric-like, with long black robes, an amulet around his neck, and face painted somewhat pale and with dark rings around his eyes and black tears falling from them. He raised his tattooed hands and called out to the party with a certain cheer, announcing that the place was a sacred place of “the Dark One” and offered them safety if they wished to cross and learn more.

A quick religion check later revealed this Dark One to be some sort of god of death, fate, or mortality, worshipped by some of the local Thakian clans and petty kingdoms. They weren’t well known, and definitely not a formal religion in other parts of the world. They decided to reject the offer, and instead leave (with the priest calling “come back if you want to learn more and sate your curiosity!” at them as they left). Hopefully they won’t be too mad about the door.


Returning to the main staircase, they returned to the pair of doors and the centipede scuffle. The spiked door had been broken down, and whoever inside was gone. Inside were remains of a camp, and some of the centipede corpses had disappeared too. They decided to check out the room, namely the “ornate wall paintings” I described. Iodas found a marble head in the remains of a statue that was in remarkable door continuation, while Nieven discovered a secret door hidden behind a stone panel. He decided to blast it with an eldritch blast, failing, and Athoz stepped up to pry it open with a crowbar and some lifting.

It led to part way along a corridor. To the left, the corridor continued into darkness, though of more pressing concern was a gnoll warrior who, alerted by the loud banging of the blast, was growling at them. He was in front of a door, and others could be seen and heard behind them.

Randomness helped them here though, as while this standoff was happening, an alarm cry from further away followed by a “charge!” in Thakian. This kicked off a three way combat between the party, the gnoll guards, and a band of Thakian hoplites who had entered the caverns to drive off the gnolls. The Thakians seemed allied with the priests from earlier and, in a case of “the enemy of my enemy is my friend”, joined forces temporarily to take down the gnolls. Five gnoll warriors, two gnoll archers, five hoplites, and three adventurers. Athoz was downed at one point by arrows, and Nieven almost met the same fate was it not for a hellish rebuke that annihilated the offending archer. The hoplites protected Athoz while the gnolls were hacked down, the survivors surrendering as they were trapped in the guard room.

The sergeant leading the hoplites, a woman with the same black facial markings of the priests, spoke with the party on how to divide the spoils. She was not terribly happy to deal with adventurers, seeing the caverns as belonging to her people. Iodas and Nieven argued that they could be of use to each other, as the party could help them in fighting off the gnolls who had made their lair in the Thakians’ sacred places. She told them to speak to the priests if they wanted to work further with them, and hashed out a deal for the immediate spoils. The party could take the material loot, and she the captives (for the priests to interrogate). The party argued to take one of the captives, to ask them for information on the caverns and perhaps convince them to into joining them. The sergeant agreed, and healed Athoz to 1 hit point through some lay on hands. The hoplites left, the party hoovered up what trinkets and coins the gnolls had as well as all the weapons, and left the caverns.


While they didn’t level up, they are most of the way there. The marble head was worth the most, and the trinkets added up eventually. They also now have a captive gnoll, who Iodas is planning to treat well and try to convince into helping them navigate the caverns in the future. While the rolls haven’t been made yet, it’ll probably be likely if Iodas shows he is the stronger leader, and will reward them with gold for their service. I’m using hireling/companion morale rules and such, so they might start with a low morale, but the gnolls of the caverns are raiders and tend to follow the strongest. Those who follow the minotaur king have little concern over nations and family bonds. Other gnolls perhaps, though not these particular ones.

All in all, I’m really happy with how things went. It was my first time running for the open table, and while some streamlining could help (namely printing off all my random tables and dungeon key) I am excited to play again.
