Cragscleft

This sprawling fortresses' name strikes fear into those that hear it. Cragscleft stands at the base of the mountains at a great breach into the Underdark.  Imposing.  Massive. It houses prisoners from all over Novaura. The Drasillian Empire gladly will collect the unwanted criminals of the world in exchange for coin and the nations of the world are all too happy to oblige.
Convicts are shipped from Shalebridge to await processing and transfer to Cragscleft after which they are put to service with any talents they have. Those that can fight guard the breach. An indoctrination process begins here preaching the glory of the empire.  It rewards going above and beyond with praise and extra rations.  Particularly valorous service is often met with early release. The integration back into the Empire has caused the population of Drasil to diversify quite rapidly - and with valuable skills.  After release promising new citizens are offered employment within the Order of the White Rose.
Unfortunately for dragonborn, or any resident of the Tetheas Dynasty release is never an option.
