We're referencing Dominions 5, an incredibly creative high fantasy grand strategy game where you play as a Pretender who's just enthralled an existent culture. As the previous Over-Deity is dead, you're now on a race with other Pretenders to seize and consecrate the sacred places of the world, be it through mortal strength or by rediscovering apocalyptic magics (unless it's a small map, it's probably the latter).
Once you do so (and hopefully it's you), your Pretender ascends beyond fantastical sorcerous power and into true divinity, subjugating or casting down all others and beginning an eon of uncontested celestial domination… until, eventually, the same fate comes over you as the previous Over-Deity.
A strange ennui overtakes you; you lose all interest in the world that is, instead strangely fascinated by the siren song of distant stars. You grow more and more passive, until, eventually, you disappear entirely, banished to places unknown. Once loyal vassals, new children, ancient enemies locked away- all realise your absence, and the ultimate prize now freely at hand.
And so the cycle begins once more.
