Spirits, afterlives and Clerics.

Moved to the Help Desk.

@Shiro: You're being polite, but in the future, just leave questions like these to the moderator team (although in your defense this was posted in the wrong forum). Especially questions like his that aren't necessarily in the Rule Index somewhere.

What happens to the souls of the dead if they follow a religion? Are they just trapped in the Spiritverse, or can they go to their afterlives?

From what I believe, our Spiritverse isn't an afterlife. It's more akin to the Emerald Dream (WoW) or the Fade (Dragon Age). No one knows what happens to secondaries when they die. They simply cease to exist in the Omniverse, much like Primes who willingly leave. After that, no one is certain because no one has left the Omniverse and returned.

Omni may have more to add to this.

Also, if clerics call on Gods for power, would that not mean there is a connection between those inside and outside of the Omniverse?

There is no connection with 'the outside world.' Characters like they would have to find a new surrogate from which to draw inspiration.

If Inlumia made a talisman to absorb background magic and sent it to his Gods and totems, would it be able to work?

What is 'background magic'? You'll need to provide a lot more detail about what you'd like to do. Do you want to have some sort of totem that you charge?
