I mean, we see him dead in Tribunal, but I was dissapointed to learn that one of the three god-kings of Morrowind is almost totally devoid of interaction. He also seemed to be just as interesting as the rest of ALMSIVI. Does anyone know what the idea was behind this? Was he supposed to have more content but it was cut?

Nah, he's just supposed to be dead. Everything with Sotha Sil is basically one giant "haha you'll never get to see this" gag from Bethesda.

We where never meant to see him then they forgot to fix the bug when he turns up dead anyway no i have no idea what they where thinking.

Well that makes me sad :[

The way I think about it now, is that he seems more interesting than the others.

But we'll never know :[
