I noticed in the OOC start area of the module, there are 4 folks listed as having completed an 'escape quest'.

I've heard rumors that other players have successfully completed these sort of quests in the past.

Is there a comprehensive list of folks who've done it? or were the ones in the OOC area the first to complete such a task?

That's everyone, there.

That's everyone who managed to complete an escape quest without dying in the process. Fugue-quests not counting.
