A coincidence .....or not? ( It has spoilers )

Well did you all remember that Haldrath, even if he was already dead, his body didnt descompose. Maybe thats a clue, maybe not.

Thordan VII seemed to indicate the lack of decomposition in Haldrath had to do with him taking Nidhogg's Eye into his body.

You sure? I watched that cutscene lots of times, and there were not specifications

Archbishop Thordan VII: [The right eye of Nidhogg] has lain here, joined to the person of Haldrath, the first Azure Dragoon. For though he learned to harness its power, he was ultimately consumed by it. Even in death, his body decays not─a pitiful end for a fabled hero.

is the text in question. It's not an explicit explanation but the way it's written makes me think that it's implied that the eye consuming him is the cause of his body's unusual state post-mortem.

For now I totaly agree thats the reason why he has not decay, but well that doesnt mean that is not something that could be easly be changed.

It also reinforced when his body vanished once the eye was removed.
