PC Gamer’s guide explains how to complete the Blasphemy quest in The Blood of Dawnwalker, a prologue mission whose outcome affects the evening’s Blood Mass. Players help Gremla recover a tapestry depicting a vampiric scene before nightfall, then decide whether to return it or protect the thief’s secret.

After inspecting Gremla’s loom, following footprints and a cane trail, and examining a bloodstained scrap, players identify Premysl in north-east Laslea as the thief. Returning the tapestry earns money and experience and saves Gremla; allowing Premysl to keep it grants a Daylight Amulet, but Gremla is killed and displayed in the church. The guide says the choice appears to have no consequences beyond the prologue.
