>>714945052Big schizopost in the beginning, given that the general community consensus is that the Dung Eater is just an edgelord that eats shit.
The majority of people say that, so they literally can't be the 'same retard'.
He thinks he has the soul of an omen, but he doesn't because he's just a psychopathic killer who enjoys being hated. While Omens are normal tormented children that are twisted into being brutes because Marika locks them in a sewer full of shit and sends Omen Killers to murder them periodically. The Dung Eater likes that for the aesthetic, not the material depth of them.
There's no reason to think that the Dung Eater is exceptionally old, like you want. His sun medallion is explained and it doesn't have anything to do with the Giants directly, "The heavy, sun-shaped medallion represents both the guidance he once saw, and the ring to which it will one day lead." He once was revived as a normal Tarnished but lost Grace, but dreams of one day making his own shining light with his Cursed Rune.
There is a link to the Giants via his spinal cord sword. But that also fits with his fetishization of everything the Golden Order hates and him being a sadist that likes mutilating bodies. What better than mutilating the last pygmy Giant for a sword. Perhaps he was a part of Godfrey's army and got the sword then, but that is really just a possibility rather than a probability.
The most glaring issue is that he literally never talks about the Crucible and isn't linked to it any item descriptions or dialog or anything.
His armor being vaguely similar in color to the Crucible Knight armor isn't meaningful on its own because there are multiple armor sets of a similar color in the game. The Rakshasa set has the same color as it and there's no link between them and the Crucible, either. While others, like Godfrey, who we know are linked to the Crucible, wear normal armor.
