Sise Fromm's stronghold

This stronghold on Annoo served as Sise Fromm's base of operations during the early years of the Galactic Empire. The base was destroyed in 15 BBY when the resistance fighter Thall Joben sabotaged the Fromm Gang's weapons satellite, the Trigon One, sending it on a collision course with the stronghold. Fromm was able to evacuate shortly before the impact turned the structure into a crater.
