The Thieves' Maze (also known as the Thief Warrens) is a long labyrinth in Baldur's Gate that leads to the Undercity. It is only accessible by going downstairs in the Thieves' Guild.
Guide[]
At the beginning of the maze the party finds Voleta who has been injured by the fleeing Sarevok and tells the player about the labyrinth ahead. Throughout the maze there are many traps and creatures, which include Green Slimes, Gray Oozes, Mustard Jellies, and Ochre Jellies, one or two Doom Guards, and Skeleton Warriors. The first two Skeleton Warriors to be encountered are extremely difficult to defeat; they have very high magic resistance. Before those skeletons, there are two traps; one that triggers a lightning bolt to fly down the passageway, another causes a fireball to fly toward whoever sprung the trap. These traps, like the rest of the traps in the maze, have a green stain on the wall adjacent to them. At the end of the maze is Winski Perorate. He also has been injured by the fleeing Sarevok and he will reveal his role in the plot and Sarevok's plans. You can kill Winski at this point although it will result in the normal loss of reputation for killing an innocent.
