The man who swung the sword said he must complete a challenge in order to get into the school. The challenge is to slay 500 Rockworms, but to slay a Rockworm he has to buy a donker. (A donker is a type of weapon that's like a hammer but enchanted with powerful magic.) To buy a donker he'd need to find the Enchanter's Shop.
On his way there he got stopped by a short old man. Somehow the old man knew where he was headed and told him not to go there, saying that if he chose this path then he would die a tragic death. He kept walking, shrugging it off thinking that he was just a crazy old man. Once he got inside the shop he saw millions of weapons even he'd never heard of. He started looking around seeing all the massive knives, giant warhammers, and even a few magic wands. Though none of those things were what he needed. All he wanted was a donker. He looked around for hours and hours trying to find one, but he just couldn't see any anywhere.
He finally decided to ask one of the workers where they were. As the worker was taking him to the right shelf, he saw the short old man staring at him through the window. He once again just shrugged it off as it was just a crazy old man and continued following the worker. Once he finally got to the shelf he had to choose what kind of donker he wanted. Their were hundreds of kinds that he could choose from. He decided to get a heavy donker and a flame donker. He got two so he could merge them together and get a heavy flame donker. He walked out of the store with the heavy flame donker and went to the forest so he could start his test to kill 500 Rockworms.
