It was ceded to the DeepCourt to make up for the Rending. While we Selkie were the ones who suffered the Mer took stewardship of her 'for us'. As much as I hate to admit it they've done a fine job. The dry landers live in clean and well managed land towns, citizens of the DeepCourt thrive in her harbors and its economy booms thanks to her brisk trade in flowers.
And the basking, oh you have not basked until you've basked on a Xerxine strand.
Just don't go to the south tip. That's where HighCourt nobility go to their final rests, there's something funny about their graves. Then there's the Deep Old One who lies near Dagger Point. No one swims or sails there. Sometimes dry landers feed their own to the beast.
