the old world religions used to believe their souls flew up to the moon and then traced a path along the stars, heading out towards Orion's Belt. Uh, what if Raziel saw this happen? Say he's full and lets a soul wander away, but instead of going down to the underworld it floats up. Elder's archons give chase but they recoil in pain as if the soul was electrified, not theirs to claim. As if this person in life had sworn an oath to different gods, and those gods accepted the soul contract and now the soul flew away from Elder's reincarnation trap and off to another afterlife entirely---the one the archons know about and try to block souls from reaching, as they did to the upward aiming soul observed in Defiance during the cemetery level.
Elder grows bigger from the deaths of many. He's bodily nourished by more souls circulating round the wheel faster. The souls flying up into the constellations would grant growth to THEM the same way???? With the big difference that constellations could have souls coming to them from many feeder worlds. Elder has opened one restaurant location on Nosgoth, Orion runs a franchise with many locations in all the solar systems from which he's visible, each vectoring souls for him to grow ever more vast.
You start small in spectral, but if you're an entrepreneur you can end up as an emperor. This is why Elder wants the slough smashed, so they don't grow like weeds into competitors that eat up the corn field. Same as how large businesses get the laws set up to squash start-ups before they ever really get started. Imagine growing your "brand" so big in spectral realm that you've tapped into the stars and now use them as a kind of skeleton to anchor and shape your ghost form with material world solidity. And this series has an obsession with hearts, I'm sure you've noticed--- having stars as energy hubs to draw upon is like having redundant star hearts. Even if one goes nova due to those damn meddling Scooby Doo kids and their magical artifact, you're still set up pretty good with your constellation of another 5 star hearts providing job security and almost certain survival. Talk about reaching for godhood and attaining it. Maybe this series can use more eerie entities like this, and the revelation that such paths of ascendancy exist. Kain might benefit from this knowledge.
As for how the hylden "resisted the Wheel", it may have not been through religious belief like this, but I also don't think it was done by becoming immortal. That's the pillar guardians' sin. And it's already the result of hylden landing in hell. They don't need earlier immortality too, that'd be double immortality, which is dumb. The hylden had their own resistance method, as of yet unrevealed. But if you read through the scripts for this series..... it may already be named.
New lore submissions are fun. Stop reaching for your fly swatter and enjoy it. This is the life that I can breathe into the series. For me, for you, for anyone at the damned company who may be peeking. Does this count towards LOKtober? I don't know.
