Why are there no pictures of flying dinosaurs?

Meanwhile:
1. Why doesn't druidic nature magic work there - surely this is a place of such uber-nature that their spells would do incredible feats of wonder?

2. Why doesn't sorcerous magic work? It's natural!

3. Why doesn't warlock magic work? Or does it? If not, it's a natural ability - it should! If it does, Yaaay!

4. Why doesn't warmage magic work? It is merely a force of the soul expressed through aggression?

I like it
