just change map to NA and pick a point to move on na map and it should be done
Incorrect. If he's on EU he need to go to one of three locations.
First Is the Tundra, crossing in the tundra is one location. The next is The desert. The Third is controlled(on both sides) by clans that don't like travelers but it's in the steppe.
To cross, you go the the stated locations up above. Then depending on which side you're on, you click the little icon that says "Viewing: EU/NA" and adjust it to the other side. Once that's done, you click somewhere on that map near where you are(IE the desert if you choose desert).
I also make the assumption that you know what terrain types NOT to cross, and otherwise with this statement.
