You're more than welcome to use sense on Elidibus. (and discern his presence in his aetherial form when applicable if you haven't come to my permissions page. I am too lazy to check right now)
Elidibus is a member of a race of Ancients. Most got their souls sundered into fourteen bits after a series of fucked up events. Elidibus was one of three who survived intact.
These ancients were comparable to gods. They had the power to create from the fundamental 'aether' (a framework of energy in all things that are needed to sustain and give life) not only objects but beasts, land, wonderous monsters. They even created a literal god (or a will for their world so it could rewrite the fate of reality and save their world).
Elidibus sacrificed himself to become the heart/soul/core of said god. The one thing the Ancients couldn't create was an actual... well, soul. So someone had to go. That someone was eventually Elidibus. But then he heard his people needed him so he sang the song and yeeted himself out to try to help. (spoiler alert, it didn't work)
After the sundering of souls, Elidibus and the two other Unsundered cast off their mortal flesh and ascended as immortal... well, spirits (called Aetherial Beings). They have since lived some 12,000 years trying to bring their world, god, and people back into a whole piece.
Elidibus is currently in someone else's body. The OTHER SOUL of that body had left 100 years of its time before. This may be picked up on if it's within Ryo's capability. But with Elidibus inhabiting it, it's a perfectly living body. Just not HIS body. Also the body MIGHT have a bit of lingering 'was once a corpse, now it's fine'. But it's okay, the original owner doesn't need the body anymore! It's fiiiiine.
Oh he also henshined up into another godlike being that embodied mankind's hope as the OG Warrior of Light before he ended up on the train. But he's de-henshined now. So there's that too.
TL;DR So he'd be a hotspot of lifeforce, 100%. Probably godlike level. Is in someone else's body (body doesn't have og owner's soul but is perfectly alive because of occupancy).
FFXI Spoilers!
