I've been researching this lengthy eclipse and I believe it to be the work of Claw Vipers.
Find their temple beneath the desert sands and you may find the source of this curse.
- Tainted Sun Altar is in pit in center of area, accessed via stairs to south.
- Fangskin and minions may be avoided by turning right from entrance and going to north around Altar: they cannot follow down stairs to Altar due to their size, so once characters have descended they are safe from them. Even if they are not avoided, it is safer to turn right and start clearing area to allow room to move and retreat.
- Click on Altar to destroy it.
I've been speaking with Lord Jerhyn, and I sense that he is becoming more and more agitated by something. You should try to talk to him again.
If he still won't take you into his confidence, seek to prove yourself a bit more. I gather that his respect for you is growing.
