This is the story of a great Storm. One that swept across the world, wiping everything out. Electronics at least. The few that managed to survive the catastrophic event were afraid and crippled. Somehow they pulled together and survived though.
After quite some time, they rebuilt vehicles, at first to simply transport. But in time, fierce leaders created war machines and gained followers. One such gang was known as the 'Rippers'. They were the most feared throughout the lands. They came after Dark settled over the sands. Plundering and stealing from anyone who questioned their methods. Killing most of the population. Then there was an uprising. Another group was formed, this one named the 'Fowl'. They were known for stopping the Rippers and taking secretive approaches to their problems. Their ranks were mighty and even more feared and respected than the Rippers.
Then, they suddenly... Disappeared. Like they never existed. Year after Year passed. No sign of them. This was enough time for an organization to form. Riggers.
