Caer Callidyrr

Capital of the island of Alaron, in the Moonshae Isles

Just like the entirety of the Kingdom of Callidyrr, the city of Caer Callidyrr was ruled by His Highness, High King Sovereign of Callidyrr and monarch of all the lands of the Ffolk. King Reginald Carrathal held the title circa the Year of the Bloodbird, 1346 DR and after the rebellion of the same year, the Crown of the Isles was claimed by Tristan Kendrick. The title then passed to his heir, High Queen Alicia Kendrick, and to her descendants. By the late 15th century DR, the title was held by Derid Kendrick.

By the late 15th century DR, House Kendrick remained the nominal rulers of the Moonshaes but had lost much of their control over the isles, and by 1479 DR, their kingdom only encompassed much (but not all) of the isle of Alaron.

Isle of Snowdown was controlled by the vampire Lady Erliza Daressin, who was loyal to Amn.
The Isle of Gwynneth was controlled by the Kingdom of Sarifal, which was ruled by High Lady Ordalf.
Oman's Isle had come under the control of a tribe of fomorians who had crossed from the Feywild into the Moonshaes, and was ruled by Queen Connomae.
The Isle of Moray was under the de facto control of the Black Blood tribe, a group of Malarite lycanthropes.
