Sort of stuck and not necessarily looking for the out and out answer but just a nudge in the right direction would be nice.

I believe I know who has the key to the back hallway guest area access, but either he is a rare pop in the dining room or I'm looking for the wrong mob with said key (the one that lets you into the food vendor area). He's not listed on Allakhazam either if it's the correct mob.

I'm also looking for some grave yard dust of some sort, which I believe is located in the unlocked crypt but we haven't be able to search that area fully and after a few runs of looking around haven't found anything just lying about. (This goes with the polishing liquid we did finally find in the laboratory).

A little info on either would be appreciated.

Nm about the dust, found it where I expected it to be.

However, if anyone knows who drops the key for the guest wing, I'd rather not have to do some funkified pulls/CoH garbage to get in there proper.

where did you find the dust

The mobs that drop the key are listed on Allakhazam, and you are looking for the wrong mob.

The dust drops off gargoyles in various zones...it's rare.

It's a recent addition then, or you are wrong. Gaorgoyles drop dreadspire gargoyle dust usually.

The graveyard dust the original poster is speaking about is needed in one of the lens quest.
You can found it in the east crypt.It's a ground spawn.
It can be difficult to spot sometime as it pops random around or in the coffins.
It doesn't pop in west ( locked ) crypt.

Yah, 4 hours of sleep does that to me. I don't know why I was thinking the post was about gargoyle dust, the grave dust is in the unlocked crypt.
