Anukan revealed a map of fœnum a ways back to show where everything is.
Latitude and longitude are not indicated on this map, but just based on where Rein (white) is located, I'm going to guess the view is centered on the planet's axis of rotation. That is, assuming this universe functions like ours, and gravity demands that matter coalesce into rotating spheres. If it is the case, though, then yeah, Rein is just about at the north pole.
