The destruction of the Lambent Brumak under Jacinto Plateau secured victory for the Coalition of Ordered Governments, flooding the ancestral home of the brutal Locust Horde. Sinking the plateau flooded the underworld of Sera, killing millions and forcing survivors to flee to the Seran overworld. A great many Locust were separated from the Queen's Remnant of the Horde; without the guidance of their Queen, the lost Locust descended into primitive tribes, they themselves changing forever.
Out of all the Locust, the Kantus priests were hit the hardest - - they reverted to primal, shamanistic ways and their healing screams descended into a dark, melancholy tone. According to records, few sounds can replicate the terror from the screams of a Savage Kantus.
