You are all prisoners/slaves who have been sold off to an alchemists guild known for its amazing transformative potions and elixirs. They ship you and a bunch of other slaves to a penal colony in the far corners of the world, where the alchemists have their greatest kept secret:
In the caves below this specific spot live a species of tentacle monsters, found nowhere else in the world. They have incredible properties including the ability to change color to blend in with their environment, a venomous sting that induces extreme arousal and feminization in men, and oviposition to lay clutches of eggs in the wombs of their arousal-incapacitated victims. Strangely they can't survive outside of the caves. They literally just fucking die if you take them outside, like a switch getting flipped. No one knows why.
The eggs, and the bodies, of these creatures are of incredible value to the alchemists, the base materials for some of their most powerful potions. They use slaves to... well... 'gather' them.
Every day slaves are sent down into the tunnels with a bag and a wooden club. If they can successfully bag a tentacle monster without getting transformed, great! If they get captured and filled with eggs instead, don't worry in the guards come through with much better equipment every few days to gather up the people who can't make it out themselves.
In theory, every contract has a debt amount to it and the resources you bring back pay off that debt, and you can earn your freedom. But they use company-store tactics to find ways to rig your debt. And no one REALLY knows what happens to the people who do earn their freedom, because this place is still a secret.
Can you find a way to escape this prison? Can you keep your manhood until that happens, or is intentionally letting yourself get egged up to pay off your debt as fast as possible the better option? Where do these monsters keep coming from, whats down in those caves?
