What kind of projection is that 2D map? The majority of map projections (especially ones that are rectangles and not some weird shape) stretch the pole out along one or more edges, so it's pretty common that such an edge has to be filled with all land or all sea. To say otherwise means that the pole is right on the coast somehow. That COULD happen, but it's unlikely. That also gives you an odd channel that cuts through your southern continent and stops right at the south pole (but there might be some interesting canonical explanation for that).

Relatedly, anything that seems to "point" at the top or bottom edges of the map is pointing at the pole, so it looks like the north pole has three continents converging on it. Again, narrative significance reigns supreme, so if it's all for the point of telling a good story, then it's absolutely fine.
