There is no Grim Reaper in the lore of Teleleli. Neither the God of Unnatural Death, nor his consort Beautiful Lady Sebastienne, nor the goddess of winter and natural death The Crone collect souls (except that, like all gods, they may appear personally to those who die martyr's deaths).
Instead, the souls of the dead are said to be harvested by the last person to die in the previous year. This unfortunate is said to drive an invisible horse and cart. They are said to experience the single year until they are relieved as if it was a span of centuries.
