Aerda: The city of Bethel is surrounded by many smaller cities, including the four major satellites, of which Jance would appear to be most directly en route. The Kingdom of Bethel itself is protected to the West by the Ashen Mountains, which stretch from far to the south until they meet with the Sea of Morel. On the South side, the Kingdom of Bethel is relatively unprotected, leading to some dispute over territory with the Kingdom of Dalmar -- in truth, what lies between is relatively ungoverned, although the towns and cities in this middle-region pay a sort of unspoken heed to Hedrogura, which is an important post of trade, both seafaring and otherwise.
Beyond the Ashen Mountains, there is a relatively large region of semi-isolated city-states, pocketed between two large mountain ranges. Despia and Eivanrach are the only ones you're particularly familiar with: They're the largest, near the Western and Eastern edges respectively. There is a pass through the mountains somewhere on the border of Bethel, but you are not sure where, exactly.
You don't know much, geographically, about The Kingdom of Tourne, except that it is much larger than either Bethel or the area occupied by the Free Cities -- and, as mentioned, that it lies beyond the Sea of Morel.
(There are a few more details -- other city names you know, and the like -- that I'll put on the map once you make the Craft (cartography) check -- as they probably won't be useful to you before then, anyway. What you know, and where things are in loose relation to each other, is dependent on that knowledge check -- the craft check will just be to determine how accurately you can convert what you remember about the roads taken, the distances between places, et cetera, into a spatially coherent map.
Also, once you all begin riding, make Spot checks.)
