O-Lir, a Luminoth and Guardian of Sanctuary Temple, was the inventor of the Quad robots, as well as Quadraxis. Unfortunately, O-Lir fell to these machines, but left messages in a Luminoth holoprojector that helped Samus Aran return energy to Sanctuary Sector. O-Lir lamented being unable to join Samus in battle, saying "my time has passed". Judging from O-Lir's scan, it appears that O-Lir was a skilled warrior. O-Lir died defending the Sanctuary Temple against the very machines the Sentinel created to help the Luminoth.
