Tarquin has a quest. He will be next to the graveyard entrance. You need to find 2 parts of a weapon. You find 1 of the part in a tomb in the graveyard the next one should be on Bloodmoons island (Its surrounded by death fog , so if you are not undead , i dont know how you will get there).
The Sourcerer in town is someone else. He is someone that the magisters are looking for, because he is killing them. If you go to the docs fishery you can talk to the people there, he was last seen there.
Mordus is an undead that stole the shipment of Death Fog and borded it on the magister ship and the ship is on its way to Arx.
But anyway i think the quest for Tarquin is bugged. At least the second part of it. Maybe i wasnt supposed to get to the bloodmoon island so early , i managed to cross there because i was undead.
