Garn
this planet was described to Luke Skywalker by a vision of Obi-Wan Kenobi. He later intercepted a transmission which mentioned the planet. Note that Classic Star Wars: Devilworlds indicates that Luke received this transmission while practising with his lightsaber aboard his X-Wing! Luke travelled to Garn, which was a desolate world of craggy rocks and dead trees shrouded in a thick yellow fog, and discovered a trove of ancient Jedi armor. The planet was barren because, several millennia before the Battle of Yavin, it was laid to waste by the Jedi Knights, who strove to eliminate the Order of the Terrible Glare. He also discovered the Portal Desolate and the soul-snares used to trap the life energy of ancient Jedi. He managed to destroy the portal and free the energies.
