How do I get to Payon from Morroc?

[Former-GM-Circe]

Satan Morroc blowing the place up sort of put a damper on navigation.

I don't think it's now possible to walk directly from Morroc to Payon without circling right around half the world.
I'd personally suggest using the Kafra warp (it's something like 1.2-1.8k), or warping to Prontera for free using the RolePlay Tavern option on the Warper NPC, then walking to Payon from there.
