The Pelesit Urn is a Relic found in Lara Croft: Relic Run. It is the sixth relic that can be found in the Jungle Temple after collecting seven clues in the terlfth level. (Originally eleven clues in endless mode before version 1.5.68.)
My Malay is pretty rusty, but Pelesit is some form of demon. I remember something about blood sacrifices in exchange for great power.
