Hyrm Jin was a rogue Kaminoan who emigrated from Kamino centuries ago to the planet Vohai where he could conduct his own scientific experiments and studies on Vohai, without being persecuted or hunted down by his Kaminoan colleagues. He was one of the older brothers to Lama Su and master to Lama Su's son, Loryn Su, who served as his assistant. Hyrm then tasked Loryn to make the necessary preparations for Bagwa's stay with them in their residence.
