How do I get to Payon from Morroc?

[shayshkers]

I'm a thief and obviously started out in Morroc, but now I find that I can't walk to Payon. I've tried every route and I keep running into Mrc_fld20, a map with guards telling me I can't go further. This map has no portals and I can't seem to find a way around it. Do I have to do a quest or something?
