Is there and afterlife on Runeterra

Runeterra is full of gods, goddesses, demigods, and aspects, but do any of them, or any other god we don't know yet have a type of afterlife? I might be wrong on this, but it seems like there isn't any kind of deity of afterlife like the biblical God and Satan, the Greek god Hades, Nordic goddess Hel and so on and so forth.

What made me think if this is when I started playing Yorick and he questions if there is anything beyond in his dialogue. He also spoke with the dead since he was a child, and tried to lay them to rest. Now he tries to raise the dead to bring justice to the blessed isles. Does he bring them back from an afterlife, or are they not at rest and he uses them? In Greek mythology, if someone has not received a proper burial, they are forced to roam the earth, not going to Tartarus or Elysium. Does this work in a similar way, where he takes advantage of these ghosts?

Another is Illoui when she kills someone in the name of her god, does the person just die, or do they go to a realm of censored Japanese tentacles?

One more thing is that if a person dies, and are brought to rest, are they just gone? No afterlife, nothing happens, they just go. This is possible, but somewhat anti-climactic (I guess it wouldn't, matter but still). Plus Illoui's E rips the soul out of enemies and beats the crap out of it. This might be something made for the sake of gameplay, but at the same time it could mean there is such thing as a soul in the universe. If there is a soul, wouldn't that mean it goes somewhere?

There are other questions I have about certain champions that are undead or possessed but that's pretty much the gist of it.
