STNL

STNL, Herald of Purity, is an aeonic herald. Created specifically to its purpose, it hunts all abominations and imperfections. It can prune any feature of its enemies, possibly erasing them from existence altogether. Its Evangelion is ''The Essence of Fault''. Its form is a great impossibly sharp crystalline blade that repels all impurities.

STNL was first created to destroy Hii during the Hellbreak; however, Hii's rapid evolutionary powers proved too much for the herald, and he was instead imprisoned within E2.
