Something about the new Ascian lore

[LineageRazor]

Ah. So just because mortals require other means to traverse the barriers between worlds I didn't think that implied or meant each one had it's own lifestream.

The Warriors of Darkness were trying to cause a rejoining, because that was the only way to allow any remnant of the First to survive. They knew very well that not a single life on the First would survive the Rejoining - but the First's Lifestream, and all of the souls within it, would rejoin with the Lifestream on the Source. This implies that BEFORE the Rejoining, the Lifestreams are separate.
