Gymelo was a celestial body, an astronomical object, situated in the Gymelo system. The Gymelo system was itself located in the Bakura sector, which is part of both the Outer Rim Territories and Wild Space.
Bix Arden-Govia, a Human, abandoned his privileged existence on Bakura, a nearby planet, when he was young. He enlisted as a ship's boy on a freighter that operated from Gymelo. By 4 ABY, Arden-Govia, having gained considerable knowledge of the Shiritoku Spur area through his voyages, had made his way home to Bakura.
The Star Wars Roleplaying Game sourcebook titled Geonosis and the Outer Rim Worlds, released by Wizards of the Coast in 2004, provided the initial mention of Gymelo. In 2009, The Essential Atlas, a reference book, identified the Gymelo system, and consequently Gymelo, within grid square G-16.
