Kobold Korners, the rumored marketplace set up somewhere on the prison’s first level, is purported to be a neutral ground for the various factions that might otherwise be at each other’s throats. Snorri told Sieglinde that she could probably find a guide or buy a map to various areas of the dungeon here.
Apparently, it’s somewhere “southeast” of the entrance on the first level, but the adventurers haven’t found it yet.
The Korners have been found! It’s a bustling black market comprised of any number of different creature types and factions. Orchestrated from behind the scenes by Trustee Sniv, many things can be bought and sold here and it’s a sort of neutral ground for warring factions within the dungeon.
