Right after TNO defeated The Transcended One, a supernatural force dragged him into a hellish plane where he saw lots of demons battling each other in a distant battle field. And then TNO grabbed a weapon and walked toward the battle field, in a calmly and this-day-has-come manner as if he knew what was happening.
So can someone please explain what was happening? The information I saw in the game doesn't really provide much clues about that. I guess the battle is probably the "Blood War".
In my opinion, the ending is confusing and disappointing. I didn't get to see what happened afterwards to TNO's companions (they had been resurrected, though) and Deionarra. And I still don't know the crucial information—TNO's identity and his detailed story before he lost his memory.
