The Sinners, The Wastrels, & The Ruin Children

They call it the Glaciation.

A lethal cold swept over the world, killing everything in its wake. Cries of the bereaved fell on deaf ears, and in a matter of weeks, the world in its entirety fell silent.

Everything is now dead. The outside world is not survivable. Anyone who leaves the safety of their homes dies within minutes.

Death is inevitable. Insanity is expected. And the only survivors consist of a mob of hardass criminals locked up deep beneath the earth, a sole unit of Lazagaul military that was all-too-prepared, and an alliance of terminally ill children veiled from the world by their now deceased caretakers.
