When the Seas Boil

Lush forests have become deserts in a matter of months after the planet experienced an increase in temperature which caused extreme droughts. With the melting of ice, the sea grew and swallowed islands and coastal cities. Humanity had been just barely hanging on when a huge solar storm hit the planet and everything went dark. Without technology, and the end of the world seeming near, society fell into chaos.
It has now been two years since the worldwide blackout and so far there are no signs of recovering. Survivors constantly battle for survival against mother nature and themselves. Society had completely crumbled away and there were no rules, except for one; don't be weak. The grim reaper himself enforced this rule and the punishment was death. One of these survivors is Cassius, a disabled young man, who refuses to die. He is constantly on the move, trusts no one, and seems to only care about himself. One day, this all changes for good.
