Aha! I used the console to add FindLassal as an AR801 variable instead of a global and things appear to be proceeding normally. Much thanks for all the help!
After some thought I would guess that this means that Haz wasn't spawning as the game wasn't ready on the "vampire" side of things, but I have no clue where to look for information on what needs to be done to force it.
AranJob was already at 3, Chapter was at 3 and FindLassal didn't exist.
I created FindLassal, reloaded but nothing happened.
I then spawned Haz and the golem, then talked to Haz and the golem opened the door...unfortunately the vampire lair appears to be empty and Haz just keeps following around. If you have any other suggestions they would be appreciated, and thanks again for the help so far!

Hmm, first I would check if these Globals are what they should be (if you are using shadowkeeper)
Global("AranJob","GLOBAL",3)
Global("FindLassal","AR0801",0)
GlobalLT("Chapter","GLOBAL",4) (this means that global chapter should be lower than four)
and if they are not, you can set them to be so either in shadowkeeper or via
