[Lore] Are the Vaulters the only canon survivors of the events of Endless Legends (that we know of)? 6 years ago

The title pretty much says it all, were the Vaulters and Sisters of Mercy, the only two factions to surive the events of Auriga that we know of? I ask this as it is clear no one remains on Auriga as when we find it in the galaxy, its a barren, sterrile Ice planet. Let me know what you guys think. :)
