Start: Mercenary Bounty Board outside of Hatmandor
Finish: Giriza Sewers
This quest is fairly straightforward. It will ask you to proceed through sewers (killing the mummies is optional, but you can get exp/loot/resurrection materials) of Giriza, into a room with several people in it, including a Citizen shopkeeper (standard necromancer/assassin items) and a Bouncer, that will allow you to start the _____ quest.
After entering this room, you will be instructed to head into an empty room, and then through a small tunnel located on the bottom floor of this room. Go through the tunnel and kill 2-3 Giant Scorpions and you'll have finished the mission. Dead citizens in this area will have some auras and a low-level sword.
