The dragon smiles and says, "I am the Great Green Yvelheim Wyrm. I have long served this land by guarding its treasures and secrets. Back in the early days, great works of art and music were kept in my cave. More recently, I was granted proprietorship of the museum. In this, Yvelheim's fourth incarnation, I have been appointed Guardian of Earth. I bar entrance to those who have not yet earned the right to enter the Realm of Earth."
His voice lowers and he continues, almost embarrassed, "Actually, I'm supposed to eat them, but I became a vegetarian two years ago. So now I have to deal with people complaining, 'Why can't I get in?' and 'I wanna see the creature!' and yada yada yada... People were a lot easier to deal with when I could just eat them. Also, I'm hungry all the time now, because I mustn't leave the cave, and plants don't just walk in here the way animals and people do." He sighs.
