^It's not far fetched. It's just that it wouldn't make a difference. Red lyrium is tainted.

^The red lyrium got there somehow. There are really only two possibilities: either the thaig came first and the taint spread to the void from there, or the taint was found first in the void and the thaig was created afterwards. The first scenario seems very unlikely, because during the time of the Evanuris the dwarves did not construct thaigs. The dwarves were still mindless slaves of the titans back then.

^That could very well be the case. Maybe the void/the abyss is just the body of a diseased titan.

I think it'd be interesting to learn that the Taint was created by the Titans to curse the Evanuris for hunting them down, just to twist things up. The Evanuris then contained it in the Black City, where it wasn't seen again until the Magisters Sidereal unleashed it.

We know so little about the Titans. Do you think they had the power to do that? Or would have? They would be creating something that would be as great a danger to them as to anyone else. Truly a last ditch weapon. Like, a "we're all gonna die anyway" weapon.
