What happens to those who embrace the Targonian divine aspects

Atreus did make the ultimate sacrifice and handed over his mortal body to Pantheon to inhabit. This raises the question what happens to those deemed worthy to be a divine aspect, those brave souls who made the climb to Mount Targon's peak and survived. Those who were blessed, or cursed, with celestial powers and became divine aspects. What happened to their souls, to their Identities.

What happened to Atreus in particular? Do those targonians take their rightful place in the celestial city where they may walk amongst deities and entities of unfathomable power?

Is there a hall of heroes up there where they're rewarded for their bravery and heroic deeds?
