I could see a useful idea being that the Abyssal Exalt apotheosis is about... becoming a "good" version of the Labyrinth? The Labyrinth itself is literally the former world-bodies of the murdered Primordials, heaped and tangled together after they fell and the weight of their corpses tore through the bottom of the world. The Underworld above is a series of "shadows" of the Neverborn and their blasphemous genesis - the ideas of death and falling and shattered land carried by the Essence of the Underworld acting like a net for mortal polities to be caught by after they pass from the lands of the living. (This is also why hauntings occur; the Neverborn were murdered and robbed of the chance to pursue their desires, and so every time that event occurs again, on however small a scale, there's a chance for it to resonate off of the deaths of the Neverborn and draw in Deathly Essence like a lodestone pulling in iron filings.)That does seem like a potential route an Abyssal could follow. I think there are even a few different spins you could put on it such as turning yourself into a legion of the damned similar to say Alucard. Personally, I've always hated the whole option of an Abyssal Exaltation being able to be cleansed back into a Solar Exaltation. Similar to an Infernal there should be no possibility of reverting the transformation the Exaltation has undergone for better or worse. Therefore giving an Abyssal Exalted their own optional "apotheosis" for them to pursue only seems fitting.
The Abyssal Exalted become more than mere Exalts by dredging up lost, Dead things and giving them a new identity and purpose. They reach out to the damned and the forgotten and give them the possibility of a future by tying their Dead, hollowed existences to the animating engine of the Exaltation. I'm adding a mixture of European Dark Age literary concepts of lordship (power going out from the king to his vassals through the swearing and honoring of oaths to him, those tied to a lord being left rudderless and bereaved in the wake of his passing, etc) and my minimal understanding of the European medieval concept of 'the king's two bodies' (which @Chehrazad is eminently more qualified to speak on, if they feel like doing so), where the king and the land are one and rise (or fall) together.
Hopefully some of this is helpful to you.
