The afterlife isn't important. Christianity is a death cult so it's main concern is with the afterlife, but in Heathenry the the family, the tribe and the nation is what matters, even after you're dead.
But as a topic of interest, the afterlife:
If you die heroically abroad, you might go to Valhöll or Fólkvang.
If you die at sea you'll go to Ægir's hall.
If your a peace of shit outlaw or get bogged you'll end up on Náströnd.
If you die unremarkably you'll go to hel (which isn't a bad place).
But that's your "outer soul", your "body soul" stays in the grave as long as you exist. don't ask the soul is a difficult subject and i don't want to write about
