Nael Van Darnus [Spoilers...maybe]

[Orophin]

Pretty sure the devs said a while back that he's dead. All you're seeing of him is what the concentrated amounts of Aether in Coil are allowing you to see.

In contrast, they never came and flat out said that Louisoix is dead. They just said that the events surrounding him at Carteneau will be revealed through the Coil quest line. So whether he's actually dead or not is still up in the air.

Well I never said he will actually be alive in his return.

Also, they never said you can't fight a dead guy. The Nael in FF14ARR could simply be a manifestation created by Aether. Strong manifestations of Aether can interact with the real world as shown through Primals which are beings manifested through Aether (which is why Aether Crystals are always needed to summon them before they appear in Eorzea) and to maintain their existence they consume Aether Crystals to maintain their Aether.

All Nael needs is a steady flow of Aether to maintain his existence which Bahamut can easily provide due to his Elder Primal status.
