Orks were the slave labor at the time of the madness. And when it was truly apocalyptic they led a revolt which caused yet more slaughter and violence in a time when it was not needed. They were led by one of the few unchained adept Orcs of the time Otek the Hound Master. He trained a force of Orks in secret and liberated many Orcs. Without the protection of runes and magic many suffered madness and fled into the spellstorm. Some however managed to remain and retain their freedom. About one-hundred Orcs now live in the Citadel freemen and deathly proud of that heritage.
