After the [[Damocles Crusade]] he joined with Farsight directly.{{Fn|2}} When Farsight went into self-imposed exile after the incident on [[Arthas Moloch]], O'Vesa became a leading member of the new Elemental Council of the Farsight Enclaves and studied the [[Dawn Blade|mysterious blade]] Farsight had left behind.{{Fn|3}}

Upon Farsight's return from exile many years later due to the [[Tyranid]] threat, it was O'Vesa who first recognized his old comrade at a war museum trying to reclaim his personal [[Battlesuit]]. O'Vesa told the disbelieving museum staff that the visitor was indeed who he claimed to be.{{Fn|4a}} During the subsequent war against the Tyranids, O'Vesa and a team of Earth Caste scientists were able to develop a genetic phage that killed any Tyranid that consumed infected biomass, halting the invasion.{{Fn|4b}}
