The prison island at the mouth of Prison Bay, a black rock fortress that has held Aal Salma's most dangerous and valuable captives for over three centuries. Its name translates roughly as "the Final Ledger"—a merchant's term for accounts that will never be settled.
Vadu Inat holds three categories of prisoner: pirates captured in Salmani waters, political prisoners whose continued existence serves some purpose, and those whose crimes are too embarrassing for public trial. The categories sometimes overlap. Escape is considered impossible—the currents around the island are treacherous, the guards well-paid, and the sharks well-fed.
The prison's most famous feature is its silence. Vadu Inat has no torture chambers, no public executions, no dramatic cruelties. Prisoners simply... remain. They're fed adequately, housed in cells that are uncomfortable but not inhumane, and left alone. Years pass. Decades. The outside world forgets them. This, the Salmani believe, is worse than any physical punishment.
Some cells have held their occupants for lifetimes. The oldest prisoner, it's said, was there when the fortress was built—though that's surely legend. The guards don't discuss inmates with outsiders. The inmates don't discuss anything with anyone.
