When i went through this section, I did not have the kinds of problems trying to escape like other people did.
I'm not sure why. It might have had something to do with the way I answered Ravel's (she is in the center of the area) questions. Make sure you ASK her the way out, as well!!
Anyway, for those of you who have had problems, my understanding is that there are several ways out. I have found
two. One is to simply go to the NE portal and wait for a portal to open. Then step through it. And poof! you're
out. Another way is to step through the SW portal and you'll pop out in the NW portal. Step back into the NW
portal you just popped out of and poof! you're on your way to Curst.
I'm sure there are other ways. Send me an email if your way was different, and I'll include
it. Also, if you compliment Ravel three times, then you get another tattoo available (thanks Timmy!). Use her hair to activate the portal to the secret garden. That portal is found in the middle area, so just walk around until you find it.
