Alderaan was a terrestrial planet located in the Core Worlds, near the central region of a galaxy far, far away. It was covered by large grasslands, forests and small seas. Populated by Humans, the planet was home to a vast diversity of native flora and fauna, including the many species of Thrantas. Alderaan was destroyed by the Galactic Empire's Death Star. Long before the Human colonization of the planet, Alderaan was home to a native sapient species of insectoids known as Killiks.
