[1.2.230] Black Magician rears his head

Well, one thing you need to take into account is that it's accessible via Lith Harbour (there's an NPC there)



Circled in red where I think it is. Could be higher though, and probably is.

Edit: if that WERE a world map in it's entirety, then it would make the most sense for it be hidden under the Maple sign in the corner. Easily accessible by Lith and close to Nath. Best position.
