Sindaran Abdication.

Political event

King Aranath, Daelda’s successor, knew the elves could win most battles against men, but also knew they would eventually expend their limited numbers against the endless swarms of barbarians. Aranath renounced his sovereignty over Hârn and withdrew his kinfolk to the Shava Forest, there to establish the Kingdom of Evael. The Khuzdul deemed this act a betrayal (which they have yet to forgive) and withdrew to their mountain strongholds. So it was that the elder peoples withdrew from the mainstream of Hârnic history and the island came under the domination of men.   By 500 BT, the Lythian invaders had either assimilated or driven the remaining Jarin into exile in the wilderness areas of north and northeast Hârn. Without the influence of the Sindarin and the Khuzdul, the level of Hârn’s civilization declined.
