Here lad, you take it. We’ve been through a lot this pot and I, ever since the last Great War, but you’re too young to remember that one. I had this with me in all my campaigns after that. The Althial Border Wars, the rising of the Dragon Lords, the Dwarven Rage… Ah but I’m old and toothless now an’ it’s no use to me. Take the pot lad, use it well. At least you’ll always be guarenteed a reasonable meal
A certain culture believes that evil can live beyond the grave. They also believe that the destruction of the dead body can keep that one from coming back. Destroying the newly deceased body can destroy the soul if done properly. They first burn the body for 24 hours, smash the remains as well as possible, then burn the what is left for another 24 hours.
