Orcs originally came to Brea from across the Western Ocean just before the dragons fell into the world. The orcs quickly made peace with Brea’s ruling dwarves, who wanted to use the orcs as a barrier against a southern expansion of the new elven territories in Tezra.
Once the Orcs had established themselves in Brea, some orcs still wanted a fight, so they raided Kallasihya. The shade-elves responded by raiding East Brea. The orcs and shade-elves exchanged raids for some time, until the Kallasihyans destroyed the city of Whitetower, razing everything except for the fabled tower itself. The destruction of Whitetower brought all of the Eastern Clans together, and together they made peace with the shade-elves.
