Ortanfel Sewers: catacombs, thieves guild, hidden passages, river Board
This is a board from my homebrewed world: sewers of one of the cities. It features a hidden thieves guild, goblin merchants, and secret passages in a few places. The underground river connects the secret passage from the vault (or to the vault) in the thieves’ guild with old ruins. On the way there, fish-folk is in charge of the water gates. The map is ready for 2-3 sessions long adventure.
Pay attention to hiding volumes, DM marks, and so on. I also attached the plain map of the sewers.
I couldn’t find the catacombs I used for the final boss fight; if you are an author of the slab, please let me know so I can feature you.
