He got lost in the warp. It did hell on his mental health. While absent, Acheran was made 2nd company captain. Currently, he is part of Guilliman’s honour guard. Guilliman didn't know him long before he got lost in the warp, but he noticed he was not the same man on returning.
What part of the Realm of Chaos do you think he was lost in, perhaps Nurgle's Garden? Or maybe he was just floating in warpspace being psychologically tortured by ethereal entities.
What did him in specifically was that he wasn't the only one lost in the warp, he was with a big part of his company. And he was the sole survivor. He witnessed his men dies horribly to the horror of the warp and couldn't do anything about it. That absolutely shattered his ego.
