You are the greatest (and only) dragon on Earth, being a hybrid of all of the strongest varieties. Your power is unrivaled even by the modern machinations of mankind, and only anything short of a could hurt you. You sleep inside of a grand cave, lying at the bed of deep lake surrounded by mountains, and have lived here for 4000 years (being 10,000 years old.). Humanity has long since moved on and forgotten about your kind's history, and to an extent, you've forgotten what humans were like, though know more of them than they do of you.
