The Isthmus is in the northwestern part of Xanth, and is where it attaches to Mundania. It is where waves of humans ordinarily enter Xanth. The attachment between Xanth and Mundania is not constant, and not even continuous, but rather somewhat random.
Important Crossings of the IsthmusEdit
- The various Waves of humans
- The exiles of talentless (and apparently talentless) humans during the reign of The Storm King.
