Lebyool was a gas giant in the Unknown Regions, a member world of the Golden Empire. As it had no native population, it would normally have been classified as a "possession" instead of a "member", but it attracted a substantial interest from corporations in the Empire because it had tibanna gas in its atmosphere. When Lebyool was added to the Empire, it spurred a rush of small corporations seeking to get a foothold and become competitors with the major companies who dominated Vedros, previously the Empire's only tibanna-producing planet.
