Some of the names seem out of place.

Sea of Spiders, I just doesn't sound right, after all what do spiders and the sea have in common.

Also, the bay of the Reaper. It sounds too ominous. The Bay of Cordell would be more likely, as they would have the advantage over who could enter and exit the bay.

And with the Provençal names of Cordell, Crestvale, Wrynne, and Oaks, Mothica seems a bit foreign. Marinath is my suggestion, it has a somewhat ancient sound to it. Gives a feel that the name is older than the kingdom its self.

Beyond that its a very fine map.
