This worldwide “death curse” not only prevents the raising of the dead but also causes creatures that were previously raised from the dead to wither and die. The source of this death curse lies in a trap-riddled tomb hidden beneath a lost city in the depths of a vast jungle.
Gundren Rockseeker has 1 brother still alive that was resurrected by spell and is feeling the curse. Tell you to find out the curse and he knows Sildar has a friend in Baldur's Gate that has been working on figuring more about the curse. Syndra Silvane is a former adventure and has offered 50g and one item each to the group member from her personal vault of magic items (very rare or lower value).
