A hive of abersyn symbiotes were controlled by the Queen of Ktath'atn on the planet Ktath'atn for many standard years. In the year 0 ABY, an Alliance to Restore the Republic team invaded the current queen's parasitic hive, during which it came briefly under the control of Jedi Padawan Luke Skywalker, and the smuggler Han Solo, who, for the duration, called the queen's hive the Kingdom of Han after himself.
