Roothor saw Azazel's angels, and wondered if he should make guardians of his universe as well. He made them in the form of blood cells. Well, they weren't really blood cells, but they functioned as them. They could ferry particles along the universe, and respond to any threats against the Beast.
He called them Dryads.
Secondly, he created a lush and forested planet around a sun (really nothing more than a ball of bioluscent fungi that radiated heat). He populated this planet with creatures that looked like him, dubbing them Snivies. He named the planet Snivia.
