An osera seed was a type of seed that a mouf might carry with it.
At one point in 1 ABY, an individual from outside the Kerritamba Village was ordered by Chief Kerritamba to gather an osera seed for an ingredient in a remedy to cure the Great Tree in the Kkowir Forest.
Osera seeds appeared in the video game Star Wars Galaxies, a massively multiplayer online role-playing game developed by Sony Online Entertainment and published by LucasArts, prior to its closure on December 15, 2011.
