Don't die?

1 = 42, Meaning of Life, etc.
2 = Death By Chocolate: Purpose of Life
3 = answer to all question 1 & 2 don't answer
4 = answer to nothing
5 = comment that always makes sense

Go back to the previous map (from the "another entrance" map).

 Go all the way down to the bottom right.  There's a hidden portal there that will take you to the level below Gwinn.  There's a rope to climb down to the Cursed Sanctuary. 

Hmmm... or maybe not-  If you've already done that, and gotten down to where it says you can't get in because of a mysterious force, go back to Perion and talk to Manji...

I haven't done that myself yet, so I could be completely off base.  Or maybe not.

To add to what Trebor posted, you need to be level 50 if you talk to Manji. He'll has for 10,000 mesos for access to Barlog, and with that, I believe you can get to the last of the Sleepywood explorer quest.
