Gheleon

Gheleon was a Hunter and one of the Iron Lords, a gifted analyst whose allies usually accepted his battlefield assessments. He was one of nine Iron Lords to reach the SIVA replication chamber in an attempt to shut down SIVA production. Jolder sealed the complex with the Lords inside, and Gheleon died there with the exception of Saladin.

Centuries later SIVA reanimated his remains as the Remnant of Gheleon, a SIVA-human hybrid. The Guardian destroys it in the Iron Tomb mission of Rise of Iron.
