When the vizjerei were shattered, most of the Lords such as Sarnakyle left to wander the world in search of rediscovery, and to learn the elemental magic that had saved them from Bartuc and his demonic army. Sarnakyle has spent two years wandering Sanctuary in search of knowledge and to learn and polish his elemental magical abilities.

If the demons established a foothold on Sanctuary, they could assault the very gates of Heaven from Sanctuary, while the forces of light couldn't in turn besiege the demons for their inability to appear and enter Sanctuary. This is why Assur has been sent. He will be victorious.
