A minor character in Fate/Grand Order. He is a member of Chaldea Security Organization who betrays them at the start of the story, resulting in the deaths of most of their employees and the catalyst for the incineration of humanity. He is the host to the Demon Pillar Flauros, and commits suicide in other timelines instead of allowing humanity's destruction.
An artificial intelligence based on him appears in the Paper Moon Ordeal Call named Lainur Guison.
He is revealed to be the true identity of The Chaldean and takes the form of Psuedo Solomon.
