Notes & Tips
To reach here, you need to interact with The Narrow at The Gullet. Turn right first, then go forward until you see a merchant stall, the entrance is behind a curtain. You'll be met by a local gang which demands payment from fresh faces. You can pay them, lie to them or just cut them out (diplomatic replic is also available, but these guys are diplomacy-proof).
This place is filled with Merchants, even an assassin. The Medicine you need for Harsh Medicine, can be purchased from Ernezzo (800 cp). If you dont want to pay him, you can kill the Spindle Man for him. But be careful, Spindle Man's guards can read your mind. Alternatively, you tell the plot to Spindle Man, he suggests you steal the medicine from Ernezzo.
A pet, Algol, can be found in the passage to Spindle Man's store.
