The Glarus Valley, situated on the world of Alderaan, served as the original homeland for the royal House Panteer. Furthermore, it housed both Castle Panteer and the [Elysium], and held the distinction of being the center for both culture and democratic ideals on the planet. This valley provided a setting where the Alderaanian aristocracy could settle their disagreements without resorting to violence.
During the era of the Cold War, the valley transformed into a war-torn territory, with the House of Organa and House of Thul retaining a limited presence there. Moreover, the well-trained troops of House Ulgo progressively strengthened their control over the area on a daily basis. Whispers circulated that the royal family remained concealed within the Glarus Valley, hidden in locations that even House Ulgo could not discover.
