Also, if the dragon is a bad parent, dragons are mostly solitary beings. They are innately self tough, intelligent, cunning and strong, and their endurance is immensely more than all mortals. He also provides for them very unusually well, for someone who tends to only sleep. Sauranath didn't know why he should look out for a magical tree that does what the Sun is supposed to do for the world down below.

I gotta ask, why did Sauranath burn down the tree to begin with? It wasn't hurting his dragons or aiding in their destruction. Does he just hate light?
