Don't want to deal with Scion but still want to enjoy the Worm-verse? I have the solution!
Powers don’t come from Entities, instead Shards are a symbiotic species. When a colony migrates to a planet and nests, it grants the inhabitants powers. After some time, the Shards will reproduce and smaller colonies will migrate to other worlds. None of this brings about the end of the world, you're safe. (You lose the ability to pick perks or drawbacks related to Scion/Eden and specific ones related to Entities)
However, through some strange twist of fate, Cauldron still exists. Doctor Mother has found a dying colony of Shards and is exploiting the corpse to create vials. Eidolon still created and controls the Endbringers. With no Entity in charge, the rules are slightly different. Powers slowly grow as they are used and the Shards grow with the user. The world no longer exists on borrowed time, except the one imposed by human nature that is.
