An osera seed represented a specific kind of seed that could be found in the possession of a mouf.
During 1 ABY, a person not native to Kerritamba Village received instructions from Chief Kerritamba to obtain an osera seed. This seed was needed as a component in a medicine intended to heal the Great Tree located within the Kkowir Forest.
The concept of osera seeds was featured in the Star Wars Galaxies video game. This massively multiplayer online role-playing game, created by Sony Online Entertainment and distributed by LucasArts, existed before its shutdown on December 15, 2011.
