A Starship "stronghold". About the internal volume of the Dromund Kaas/Coruscant stronghold, two decks (one command/crew, one engineering and cargo bay/shuttle bay), with reasonable sized compartments and bridge (Christ... enough with basketball court size areas, especially the bridge) with the textures of the Rishi Patrol Carrier.
It's Star Wars, that there is no ship personal "stronghold" is silly, come on guys. And no, guild flagships do not count!
