A fortified position located on the planet Annoo acted as the central hub for Sise Fromm's activities throughout the Imperial Era. This base met its end in 15 BBY when Thall Joben, a member of the resistance, executed a sabotage operation targeting the Fromm Gang's weapons satellite, known as the Trigon One. This caused the satellite to crash directly into the stronghold. Fromm managed to escape the premises just before the devastating impact, which obliterated the structure, leaving behind only a large crater.
