The castle encompassed the tower that served as the site of the ritual of royal succession on Tammuz-an. Inside the castle, the rulers were seated on a throne encompassed by a massive statue. When in negotiations with foreign dignitiaries, King Julpa used a separate meeting room that contained thrones for the leader of each delegation.
The fortress contained a vast, centuries-old dungeon with an extensive system of tunnels. Dangers inside the dungeon included a pit containing a durkii, hallways lined with ancient battle droids, a lava pool, as well as rooms with trap doors and closing walls. Mon Julpa's father had taught him about a secret entrance into the dungeon, which was used in an attempt to reach the ceremonial tower in secrecy. The dungeon also contained a prison, which was used to house criminals such as the pirate captain Gir Kybo Ren-Cha and his gang.
The castle also had a massive hangar where groundcars, Imperial Side Gunner vehicles, as well as several squadrons of R-22 Spearhead fighters, Imperial Sniper Vehicles, Floater-935s and Ubrikkian Airhooks were stationed.
