An insular world in a small system, Daegox 4 is a planetary-scale prison. Aside from its wardens, all inhabitants here are prisoners. Two hundred years ago, Daegox 4 was a wild planet, inhabited only by native flora and fauna, such as towering kaezar trees, grasslands of waving tchothein, herds of docile rimbets, predatory felrots, giant buzzing skivvlers, and the soshsurus fungal network that forms a global mesh in the planet's oceans. Then the Daegox Corporation discovered the untamed world and claimed it, quickly building prison structures on the planet's lush surface. The corporation's members are all mysterious beings who call themselves 'wardens'—humanoids with crimson skin, black eyes, nearly transparent hair, and six-fingered hands. The corporation accepts prisoners from any government or entity it judges as legitimate, for a fee. One of the planet's most remarkable features is its atmosphere: the outer layer is a thin, one-way membrane that physical objects can enter but cannot leave, and teleportation magic within it is unreliable. The atmosphere also contains spores of the world-spanning soshsurus network, which make most sapient creatures docile and uneager to commit violence—though the wardens are immune. Daegox 4 has two large continents: Control, completely covered with a sprawl of squat buildings housing millions of prisoners, and Bounty, a mostly untouched wilderness where prisoners are allowed to roam freely. While some prisoners have appointed sentences, most are lifers. The Daegox Corporation prides itself on its claim of having never allowed a successful escape, though underground groups speak of a figure known as the Wren who is said to have escaped single-handedly.
