Do not enter the sewers below level 30, the following message will display 'Swirling shadows feed on your weakness, and you are no more.' and you will die with no corpse left behind.
To turn in a chit make sure you go at day time. Then go to the upstairs room labeled 4 on the map. Kill the apparition and a key will drop to the floor. Pick up this key and go to the room labeled 5 on the map. Type "unlock oakdoor" and the key will drop from your inventory and a door will open. The direction of this door depends on which side you are currently playing. Inside the next room make sure the chit is in your inventory and type "put chit chain".
