You'd think it being a Hive oriented expansion would mean Necrochasm would finally get to bask in the light of day for a little while longer while they all remained relevant to the game, since well, after this the Hive are pretty much gone. Unless Oryx has a daddy and he's still around too. But I doubt that.
Unless, no... his father is the Given King, Xyro (as in zero -blam!-s given & oryx backwards cuz Bungie loves to reuse content.) And he 'gives it' to aliens instead of using mind control to 'enthrall' them. And he too will overcompensate with a huge sword. And seek to smack you with it over and over again and glitch out doing so. And he will also have the power to reset your Exotics just as you go to challenge him in his own xpac, the effect is called 'Dark Belowing You Again.'
