The Defiant Core Base is a unfinished Separatist base, located on Innton II.
Found underground, in a enormous cavern, it is constructed from salvaged remains of the Nova Defiant.
The ship and base were abandoned and forgotten for decades until a small Rebel scout unit heard rumours of its existence.
They tracked it down and found the main elements intact, although in dire need of refurbishment.
Omega Squadron have secured and set about the restoration of this Rebel Stronghold.
