Phalorm

Phalorm, also known as the Realm of Three Crowns, was a kingdom forged in 523 DR by the Council of Axe and Arrow, compromising of the following nations:
 * Humans of Delimbiyran
 * Elves of Ardeep
 * Dwarves of Dardath
 * Gnomes of Dolblunde
 * Halflings of Secomber

Phalorm was destroyed by orcs of the Horde of Wastes and remnants of Everhorde, thus later becoming known as the Fallen Kingdom.
