The Mer-King

In the eleventh episode the Mer-King is only a name in the Baron's correspondence. Brennan says that among the five kings of the council, the Mer-King has by far the most correspondence, appears furious, has an enormous army and is waging an enormous war NA E11·00:23:20 NA E11·00:23:44. In it he writes "The time is now, I must conquer as much of the land and coasts as I can." NA E11·00:23:44, and other correspondence says "My daughter has been taken to the land and must be returned to me." NA E11·00:24:08 Brennan adds that he threatens to leave the council and not aid the war effort unless his daughter is found NA E11·00:35:32.

In the twelfth episode Mira says her father has made alliance with terrible forces and banished the sea witch, and that he can find any princess who touches the ocean NA E12·01:42:49 NA E12·01:43:46. At the end of the episode he says "I think going is out of the question!" and he and his soldiers burst from the ocean onto the docks of Toy Island, and a card names him Ruler of the Seas NA E12·01:44:16 NA E12·01:44:26 NA E12·01:44:29.

In the thirteenth episode he stands on a dais dock in a circle of churning water, powerfully magical, and calls "Daughter, I have come to claim you!" NA E13·00:06:35 NA E13·00:08:40 He bellows "Daughter, you have debased yourself with this vile new form! Come to me at once!" and Mira fails a Wisdom saving throw NA E13·00:13:12 NA E13·00:13:18. He says "The Council of Kings banishes you to oblivion!" and sea vermin swarm the party NA E13·00:14:44. The Terrible Dogfish explodes up through the dais dock and Brennan says the Mer-King is swallowed and eaten immediately NA E13·00:30:22. Brennan says Mira is no longer compelled by any magic, and later says the King is dead, having been hit by Rosamund's arrows and not having enough hit points to survive the Dogfish's first damage NA E13·00:43:34 NA E13·01:16:11. In the fourteenth episode Mira says her father was just eaten by a giant fish NA E14·00:34:48.
