A semi mobile fortress placed in the mouths of rivers, bays, and other bodies of water up to several miles off shore
"Deepbend, the toughest place to live south of the wastes. The inmates are tough, so we gotta be tougher. They may complain of 'abuse' and 'cruel and unusual punishment' but you know, they deserve every last kick"
-Darner Gearbend, Warden.
The Rock of Gibraltar, once a stalwart of British power, the gate to the Mediterranean, now is a fortress for the Eurasian Alliance. It's fair teeming with neo-Soviets and submarines.
"Ye thought the orbital penitentiary around Venus was hard ta endure? That place is a vacation spot compared to Davy's Lockdown! If the guard borgs can't find an excuse ta peel the skin off yer bones and the inmates don't use ya for their bettin pool, the pressures o' bein that far beneath the waves will drive ya to the brink, mark my words!"

It is said in the hidden myths of the banned and hunted Cult of Ma-O, that the Seamus Straits are where Ma-O fell when the god Jove hurled him from heaven. His physical body was smashed into pieces of amethyst and his spirit trapped within the warm waters. Here under the waves, once when built on dry land the pride and joy of the De Madden Company, Castle Seamus is now occupied by a unique underwater tribe.
The Nomin gypsies have a fiddling competition every year, known as the Danse de Velose. Beaters hit out the rhythm on taut drums and the competitors start to play, slowly at first. Youngsters can compete, but are soon pulled away by worried mothers, before the competition becomes too dangerous. After two hours the haunting tune has become dazzlingly fast. You can resign at any time, but the moment you make a mistake you receive an arrow through the neck. Strings may snap, but the players must play on. The whole affair never lasts much longer than three hours, and the last fiddler playing is crowned king of the gypsies.
