Gargos is an ancient creature spawned from the Astral Plane. Sadistic, vain and utterly megalomaniacal, this nightmarish entity rampaged across his own dimension, killing all who opposed him and siphoning their powers, eventually becoming the supreme Shadow Lord—a master of Shadow Energy. Gargos finally vanquished the once mighty Ichoriens; and the last good Astral denizens—the Guardians—fled that plane, escaping to other dimensions. They sealed off the Astral Plane behind them so that Gargos could never taint another world with his corruption.
