A Twi'lek male, Odumis Mer was one of many Pilgrims who followed Matriarch Kolovish to the planet Tython in the aftermath of the Great Galactic War. Assisting in the establishment of Kalikori village, Mer was appointed as the security chief of the village during the pilgrim's second decade on the planet. Angered at the increased Flesh Raider attacks on the camp, Mer desired to obtain an elixir used by the Flesh Raiders to make them stronger. Mer intended to feed the elixir to his warriors with the intent of destroying the Flesh Raiders.
