Almas
this world was the fifth and outermost planet in the Cularin System. The Jedi Knights of the Old Republic discovered that the ancient Sith had established a fortress on the desert side of the planet, hoping to gather Dark Side energy from the Force-dense Cularin System. Analysis done in the years following the Battle of Naboo indicated that the fortress had been built 1,132 years prior, well before the Battle of Ruusan. One of Almas' moons also was known to be laden with unique crystals which the Jedi used in the creation of their lightsabers. The fortress on the planet had been established by Darth Rivan, who was generally credited with bringing the kaluthin grass to the planet. At odd intervals, and often when a starship passed over its location, the central tower of the fortress would eject a huge bolt of lightning into the sky. When Darth Rivan first arrived on Almas, the planet's atmosphere was filled with poisonous gases like phosphorus and methane, so he developed the kaluthin to help alter the atmosphere. The kaluthin was a success, given that all Almas' water was located underground, and continued to thrive after Darth Rivan was driven from the planet during the Sith Wars. Over the centuries, the kaluthin spread across the planet and created an atmosphere which was so high in oxygen it was almost toxic to humans. The grass also gave the planet a distinct aural glow, mainly from the phosphorus it consumed. This living growth was unusually countered by the Dark Side energy on the planet, which originated in the desert region and slowly spread. The Jedi of the Old Republic determined that the desert area would eventually consume the fertile kaluthin plains, utterly destroying the planet's surface.
