Involvement
Viss and his mate Brathwen are both Novices of the Absolute and can be found near the entrance of Grymforge, opposite to the berth X: -608 Y: 404. They have been tasked with disposing of corpses of Deep Gnome slaves that died recently under the rockfall.
The player character can speak to Viss, but the dialogue will be actually carried on with Brathwen, while Viss only butts in several words here and there.
If not approaching Viss and Bratwhen at once upon arriving at the Grymforge, the Duergar will kicking the corspes off the shore into the deep water and eventually leave only one of the bodies intact - the very same that has the 
Fetish of Callarduran Smoothhands on it.
