Poseidon's Grave

Once upon a time, a man got sick, very sick. No doctor could prescribe what it was nor treat the symptoms. One day, he collapse to become a husk, a thing. A being now lifeless. But he was granted another life, is what he initially thought, but his illness was no accident. For the pleasure of the observing administrator, the man has to play his games, struggle to survive in a world that would rather see him dead or abused for their benefit as a dungeon. Cornered and afraid, he decides to specialize in something universally reviled by all adventurers, a water dungeon.
