From Halopedia, the Halo wiki
Sustaining Wind was a San'Shyuum elder and Prophet who lived during the Forerunner-Flood War. He survived the initial attack on Janjur Qom, but he was most likely (together with all other San'Shyuum not saved by the Librarian), killed when Master Builder Faber used a Halo installation to sterilize all life in the system.
