Re: The Fate of Stars

From Unukalhai we hear a story of another star...

the fate of another star entirely. On this other world, a magick was devised that allowed the realm's champions to use a stone known as “auracite” to contain the power of primals.

So armed, these heroic souls conquered god after god, oblivious to their weapon's fatal imperfection: its propensity to bleed primal energies. And with each victory, the heroes changed, transforming at last into fiends of endless appetite. Insatiable in their hunger for aether, they ultimately went to war over the star's ever-dwindling life force...

...And fought until there was nothing left

We know that shard 13 died to the void.
We know that shard 1 almost died to the light.
We know that 7 other shards are consumed.
We know that we are the source.

That's 10 worlds in a known state. Is this the fate of one of the 4 yet unknown worlds, or is this perhaps what caused the collapse of 13 into the shadow?

If you complete the Warring Triad Questline, it becomes pretty clear what he meant.

He was talking about how his homeworld, the Thirteenth Shard, became the Void.

Ah, I wasn't sure about that, but thanks for the confirmation.
