“The Gnarls” is a name given to the wilds near the outpost and landing pads beneath the Masters' Retreat. It was nicknamed for the thick undergrowth that originally covered the region, which took several months to clear. The original explorers of Tython discovered and restored ruined stone paths and bridges leading through the Gnarls, suggesting these wilds were once used by the ancient Jedi.
Although still a proving ground for Jedi Padawans, in recent years the Gnarls has become increasingly dangerous. Wild animals have begun migrating closer to the Gnarls outpost, and there have been sightings of Tython's native Flesh Raiders in neighboring sectors. The Jedi Council is in discussions about moving the training grounds to a safer region, but many Masters feel that risk is necessary at a certain level of tutelage; the galaxy is dangerous, and Jedi can't be shielded forever if they're to be prepared.
