Once upon a time, I found myself in the world of Percy Jackson. I was a soldier, trained in modern combat, but now thrust into a world of gods and monsters. I joined Percy's group, using my combat skills to fight off the occasional hellhound. I quickly learned about the power of the gods and how to use the environment to my advantage, like using water jets against fire - breathing creatures.
One common theme is sacrifice. As a soldier, Percy often has to make tough choices that involve sacrificing his own well - being for the greater good. Another theme is loyalty. He remains loyal to his friends and the gods even in the most difficult of situations.
