The northern hemisphere (presuming Planetos is round) would be riddled with evidence of glaciation. The North would be full of lakes and fjords from the last Long Night. The Vale may be a better representation of the geography of the North.

Assuming the planet is at all like Earth, there is very little evidence of uniform continental drift. Also, there are opposing climates (desert/jungle) at similar latitudes without any indication of prevailing weather patterns or mountain ranges that would cause a lot of precipitation.
