Testers needed.

2. Yes, one or two of them showed up, I don't remember exactly, and I killed them. There are no more Rune Priests on the map, so I think something is wrong with the quest. 5. And I thought it was done on purpose, like I have to go to their lands through a portal.

Answers regarding the editor:
1) Not all objects leave these black holes, for example, garrisons. As for the rest, I tried different options.
2) I made a texture with writing, gave a link in Haze (one of the lighting properties), and I enabled this lighting in one of the dialogues.
3) I hope they will be resurrected.

Yeah, thanks, I would never have come up with such interesting solutions.
