Things that have happened in the steam chamber collab so far:

[list][*]Narivar has been taken down alive and disarmed and the Dwemer key has been taken from him
[*]The two remaining Ashlanders that initially sided with Niernen have surrendered and been disarmed
[*]Dwemer key used to open the door, revealing shiny loot including two large ballistas 
[*]Sadri has a new spear[/list]
We thought it best to remove the threat of the Ashlanders in a single post, [@Frizan], to smooth out the rest of the narrative. That still leaves him with several things he can do, but the first one that popped into my head that he might enjoy is commanding/directing the Ashlanders (perhaps in collaboration with Edith) to help haul those heavy ballistas out of the dungeon. And, of course, helping himself to some loot if so desired. 

I think we're almost ready to wrap it up and post it.
