Blood of Innocents

I will create a toxin to bleed the violence from the Venture Company, rendering them weak and docile. That should fix the Horde's problem in Stonetalon, yes?$B$BBut to create the toxin, I will need the blood of innocents, a difficult ingredient to obtain.$B$BFortunately the Syndicate, a group of human brigands in this area, employ shadow mages... and those mages collect innocent blood for their own, unsavory purposes.$B$BYou can find the Syndicate shadow mages in Durnholde Keep to the southeast.
