Help stuck in Watchers Keep level 3

[RUDEAVENGER]

I think I'm screwed big time, went through the maze finally got to the end and gambled with that polite Demon (Aggerath something)
and found out I don't have the Scepter of Radiance, cant't remember if I left it behind or dropped it somewhere? I do have the journal and 2 scepter gems. Need help getting back to the stash where I found the journal to see if I left the Scepter there?
Any help would greatly be appreciated.
