We have better chances watching Ghaul being (genuinely) resurrected than we do Oryx. While he may have not initially enjoyed genocide, he inevitably became conditioned to Sword Logic and was willing to follow it to the bitter end. There is also the fact that his body is still floating within Saturn's rings, if he already hasn't plunged into the planet's atmopshere, making it very difficult for a ghost to simply find him much less revive him. Oryx's worm still likely resides in him too, which may block off his ability to be resurrected by a ghost. no matter how you cut it though, Oryx is pretty much [u]dead[/u]. The only way we'd ever have Oryx come back, outside of his own raid, is if he is still mentioned throughout the story, be it in lore, in dialogue, etc. If you ask me, that's the best way to "bring back" a character while respecting their death in the story, much like how Cayde is still brought up every so often in one way or another (such as Ikora's nightmare or Crow's restored memories). As far as Xivu Arath goes, she, nor Savathun, can bring Oryx back since he died in his own throne world, making his death permanent. Oryx was only able to bring Xivu and Savathun back before because they died in [b]his[/b] throne world, sending their souls back to [i]their own[/i], and he then revived them through an act of cunning and total war (or something long those lines).

With Oryx , and possibly Xivu also switching sides, would totally shake things up But it won't happen for the same reason Savathun didn't offer alliance with us in Witch Queen , we can't have too much help because Bungie has already decided that the Darkness wins

Mind you, Auryx started off as female before the all known mighty Taken King, Oryx as you all vet know it. I can't imagine him having Traveller's power against Vanguard and the whole star system. For that he should stay dead just as his sister Savathun.

No, he's dead.

I suppose a ghost could resurrect him since we killed him. Although I think he is still alive in the exotic scout rifle. So if we destroyed it, then maybe.

Oryx never brought back savathun or xivu arath. They died in HIS throne world. Do to their deaths they became so weak that they couldn't manifest themselves until oryx commited acts of war and cunning to bring them back. In order for a hive god to truly die they must die in their throne world. We never actually killed oryx in regicide, he took himself and retreated. The Dreadnaught is his throne world, so if he died in regicide kingsfall wouldn't have happened. Revival is also a direct violation of the sword logic. He exiled Nokris for necromancy. And he probably wouldn't want to be revived. But theoretically it would be possible to revive oryx as his physical body is still floating. We only killed oryx once in kingsfall. But sense his death was in the Dreadnaught his soul couldn't retreat to the throne world as he already died there. Let's say oryx doesn't have a choice. He really wouldn't be "Oryx, The Taken King". He wouldn't be able to take, nor would he be a king. If he was filled in on his identity like savathun was he would take his own life but kill his ghost first. So my answer is no. Not because it's not impossible but because he wouldn't want to.

I think Oryx coming back would be a little much. We'd be approaching Spiderman 3 levels of too many villains at one time to manage. I like this current mirror dynamic of having an adversary to ally ration. We have Mithrax and they have Eramis. We have Caital and they have Calus. We have Savathun (in theory) and they have Xivu. Adding another big bad in there throws off the symmetry.

The purpose of the light as a paracasual force can revive any dead combatant, but here's the thing: Oryx would be sought after. His worm would be that of legend as the navigator. Reviving him would bring the highest form like that into the light, but we would be facing another savathun situation. She would absolutely seek to corrupt Oryx into using the darkness. It would be interesting, but we would absolutely be rehashing Witch Queen if that happened.
