The Yildun Wormhole Junction was a wormhole junction in the Yildun System with at least three termini. It was the second-oldest wormhole known to humanity. Yildun did not include a habitable planet, but the presence of the Junction made the star system a hub for interstellar transport in the Solarian League, which supported industrial development in Yildun, including such companies as Technodyne Industries.
