Summary
Sieg is a homunculus engineered by the Yggdmillennia family for various specialized roles. Originally housed in a prana supply tank designed by Gordes Musik Yggdmillennia to fuel Servants, he was among many selected by Caster of Black to serve as raw materials for his golems. His Magic Circuits proved to be of unexpectedly high quality, leading to his selection as the core component for the golem Keter Malkuth. Upon gaining consciousness, Sieg lacks any established personality. He is terrified of everything except himself, convinced of his own nonexistence. He describes himself as transparent and colorless, reflecting his belief that he possesses nothing and received nothing from his birth.
