The Flight of the Sun
The Sun church will tell you the sleepers are demon posessed. And though the priests have, on occasion, managed to liberate some of the afflicted, prolonging their life and preserving their sanity, there is but one way to make sure the demon is banished – and that is by fire.
This condition begins with vivid and very realistic dreams. Harmless and sometimes pleasent at first, the dreams soon take a more disturbing tone, causing the sleeper to twitch in his sleep, wake up in sweat and, subsequently, lose any chance of night rest. As the sleeper grows weaker, the demon grows stronger. In time, the posessed one begins dreaming while awake, loosing the ability to tell dreams from reality.
Actions taken in such a state, especially the ones followed by memory loss, can sometimes be violent. At this point, all hope of recovery is lost and the sleeper must be fed to the flames, both for the sake of his own soul, and for the sake of others. Placing him in a cage and keeping him chained but alive will not do. Such a creature carries about a shadow of destruction; a dangerous and malevolent presence that has a mind of it’s own.
