Zoku, The Harvest

Dwarf Fortress fan art depicting a procedurally generated event in which Zoku, a human goddess of war, death, and fortresses, sent the cobalt iguana demon Istro Seareddent into the living world so that great fortresses might be raised and tested in siege. The ritual took place in Lerothima using Controlfang, a metal tablet inscribed with the iguana demon's true name.

Zoku is depicted as a mix between Athena and a valkyrie. Her domain is fallen warriors who died in battles and sieges. "Zoku" means "harvest" in the human language and she's carrying a sickle which she uses to collect souls on a battlefield. Zoku is associated with valor and glory of battle so she isn't your typical robed grim reaper death god. She's a happy reaper.
