The ones that gained immunity to diseases and other stuff due to Azath occupation were Dancer and Kellanved, the other old imperials eg Nok, Urko etc gained longevity and immunity from various alchemies given from Kellanved. Only two people were allowed in that Azath house. Maybe some of the other old guard got in there at times in a similar way that the Tremorlor crew did. But yeh that seems to be common misconception lately that the old imperial gang had access to that Azath house..
During the Nok/Tavore conversation in HoC, Nok explicitly says that the Family as a whole enjoyed the benefits of Deadhouse occupancy. It was the family's original base of operations, "absolutely secure" in his words, and they all would have had access - even Dujek, though this raises questions about his death. It was off-screen, so maybe he isn't actually dead! Dujek certainly would've had reason to want to give up his command - a broken will - and he could've been told that Paran was available to take his place...
To back up my assertions - Nok's words from that passage (p 296 mmpb)
'"...Only Ameron and Hawl and I escaped. A lad named
Dujek discovered where we were holed up and he delivered us to his new employers. Kellanved and Dancer."
"Was this before they were granted entry into the Deadhouse?" Gamet asked.
"Aye, but only just.
Our residency in the Deadhouse rewarded
us with - as is now clearly evident - certain gifts. Longevity, immunity to
most diseases, and...other things. The Deadhouse also provided us with an unassailable base of operations. Dancer later..."'
It's clear - all the Family had access to the Deadhouse, including Dujek. All the Family enjoyed the benefits.
I think the "most" there leaves open the possibility that Dujek was genuinely killed by the plague - a disease spawned directly by a goddess, if anything could kill a Family member it would be that.
There's also some confusion there, Nok includes Duiker among the Family later in that same paragraph - but Duiker thinks to himself in DG that he does use alchemies to maintain his vigour, making no mention of Azath-derived longevity. (I'm assuming this is the source of your assertions about the other Family members, which have no other basis that I know of).
And I think Apsalar is on the very verge of ascension. She needs the final push to go over the edge, a la the assassination of Dancer. I think she needs to die and then will ascend.
