To sum up the interesting points: Drew, the obnoxious main character, is actually from our world. One of the main rewards of combat is retrieving gems from fallen foes, but this can only be done when you kill them yourself, not the dragon (called Thuban). Thuban can be customised, or 'pimped', with colours, elements, and armours. There's probably more, but it's late, I'm tired, and you can read.
