"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!"
An underwater prison with a dark past, suitable for any sci-fi, neo-dystopian, or cyber punk setting.
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.
A wild species, vinus homophagus, more akin to sea-grape rather than the terrestrial variety, is not a monster despite its fanciful name. The grapes, a deep purple color when in bloom, and oozing dewdrops of perspiration, like the most prized and delectable of drinking wine grapes, do however deserve their moniker. Wine made from this fruit, is deadly to most humanoids, as is the raw berry, if plucked and eaten from the vine. It is the unnatural chemical concoction found within the fruit’s tart skin, which gives the man-eating grape its name. The chemical stew found inside each berry, functions as a necrotic agent, the same as found in some species of venomous snakes. The grapes literally eat the victim from the inside out, via cell death, dissolving organs and flesh in quick succession.
The tribes of Pra-Oohk Crater, from the jungles of Ghlush are known to sell the fermented “wine” of this grape to merchants of distant lands. Sadly, the taste of the concoction is divine when first quaffed, and even worse, the man-eating grape wine will never detect as poisonous via mundane means, its horrid natures somehow masking all attempts. Luckily the man-eating grapes are extremely rare, and endemic to humid jungles.
