Running 1.0.7.
Here's the rundown:
Ok. That's normal. For whatever reason it seems it didn't bring the quest to a stop though. If you still can't speak to him about other stuff, leave the sanctuary and the connecting sewers, wait a bit on the surface, then come back. If that hasn't corrected things, then type this into the console:
stopquest aaaDBEdlaSQ
It might also be beneficial to know what stage that quest thinks it's at, so if you could, grab the output of:
sqv aaaDBEdlaSQ
Once that's all done, you should be ok. No need for whatever heroic measures you had in mind with that extrication spell.
Spoiler When I initially explored the sanctuary, I opened the ayleid cages. Saw that they were openable, so I did! When I returned to talk to Edla, she was standing in the open cage and I didn't need the key. Don't know if that has any impact.
Also, I notice that all the ayleid reliquaries are called "Listener's Reliquary". Shouldn't some of them be named differently, particularly in the "barracks"?
The reliquaries are a bug, one I thought was fixed before but I guess not. It's fixed now though.

I found a couple of odd quirks at the next sanctuary on my list:
Spoiler In Anvil, there were two chests superimposed on each other. They are at the foot of the bed in the northern sleeping quarters in the NE corner. Also, when I killed the boss wraith, he continued to hover and make wraith noises. This might be an issue with my game because I've started to have some odd glitches since I got the abomb issue. I fixed it, but things are still acting up a bit. Anyway I exited the game and reloaded and he collapsed to the floor but he continued to twitch as if there was a collision issue. Also when I looted him, his body disappeared almost immediately. Not in front of my eyes, but I walked around the pillar and when I returned he was gone. A couple of the other wraiths disappeared quite quickly too, but not all of them. Could be just my game, but not sure what you intended here.
btw, Ocheeva has the same problem Vicente had, but I imagine you know that by now. I didn't save
all the originals, but most of them

For Bravil, I opted for Gogron. Arquen said to get the key from the Lonely Suitor, but that wasn't an option. The innkeeper didn't have the dialog option. Also, I'm not sure she tells you where the sanctuary is actually located. I peeked at your walkthrough

Fortunately the hatch was unlocked and I was able to enter the sanctuary.
I didn't bother trying to talk to Gogron - I presume it'd be the same deal.
The dialogue thing with the vanilla guys was an oversight. It'll be corrected. Bethesda and their scattered dialogue. Exile control? I mean, seriously, why there? Makes no sense, but that's no surprise anymore.
Spoiler The wraiths do that in a vanilla game too without the UOP. It's a bug in their death animation. I'll copy over the UOP code to handle that on my wraiths.
The key in Bravil was another oversight which will be fixed. Only happened if you hired the vanilla orc, because it ended the Bravil quest before you actually do anything. That will end now when you go talk to the guy to get your key.
Barnacles?!! You added a character with a pirate accent named Barnacles?! That is just too funny - loved it

I love mods that give me a chuckle every once in a while. Very nice job of incorporating the results of other mods too (in terms of characters being available).
I did, he was added as a contingency for Anvil, and it didn't seem right to make a pirate that didn't have a pirate accent
