Dead Tissue

Dead Tissue is a quest item in Pathologic, although it is superfluous. It is obtainable by the Haruspex on Day 4 in Rubin's Prosectorium. The Haruspex may give it to the Bachelor, but it is not required to progress the quest.

"This is blood and tissue of a person who died of the Sand Plague. Procuring this sample took a lot of work. Illegal dissection of dead bodies may result in an accusation of sacrilege, leading to exile at best and more commonly to lynching."
