Here's the story I had up at the fair, it's the same story just in more detail:
A long time ago an evil wizard named Zedimus mustered an army of orcs from the Gatistard Isles and attacked the whole world of Tetorna. He wanted to control everything. He wielded a mighty magical axe known as the crystal crusher, and soon most of his power was transferred to the axe making him unbeatable if he had it. All of the factions of Tetorna had to band together in the Ivory Eagle alliance to protect their world. They soon overcame Zedimus and his army by using trained eagles to steal his axe from his hand when he was distracted by the battle. But the wizard still had enough power in himself to not be killed, so they locked him and his loyal orcs in a giant iron cage and buried it deep in the Vauspar mountains. The dwarfs dwelt there and guarded him.
1000 years later the alliance still stood and helped protect them in many a battle. The memory of Zedimus had become a legend. Dwarfs mined deeper and deeper into the mountains. Soon they hit a giant solid metal wall. Through an evil spell, he hypnotized them and had them break it down and free him and his army. Zedimus then slaughtered the dwarfs and took over their home. He restarted his conquest with new smog-rock monsters that he caught from deep underground and siege weapons were stolen and modified from the dwarfs. His first goal is to get his axe back from the Ivory Eagle castle; with it he is unstoppable!
