Aibu 'Ihsam is a Sangheili politician on Sangheilios. In addition to serving as the Minister of Worship, she also serves as a Temple Master, the equivalent of a Christian priest. She is violently anti-human, and has secretive ties to the Ultranationalists.
The name was spawned in the HBO Elite Namilizer from Shi Kai/Shiek/Bungie, after the Bungie artist.
Her zealous hate speech was inspired by that of Fred Phelps.
