The Seven Magi are god-like humanoids who are known to be the gods' proxies. In the gods' absence, they now have complete sovereignty over the realm of Asgard. The only Magus that is actually a character so far is Hector, the main antagonist of Riviera: The Promised Land. Not much else is known about them, but the cloaks they wear supposedly elongate their lifespans so that they may live for eons. Though they can live indefinitely, they can still be killed by a more powerful foe, so they are not immortal.
