Artemisia M. Delgasso.
Simply known to many as the 'goddess Artemisia' or the 'goddess of Evolution'.
She was the being in the Valmone Universe's pantheon that was responsible for the 'Aspect' of Evolution.
Basically, she was the one who made sure that what needed to evolve did so, and what needed to stay primitive remained that way.
The second part was very necessary, as there were certain things in the universe that did not need to evolve; certain creatures that did not need to evolve to the point of gaining sentience and intelligence, leaving their primitive instinctive states.
However, as far as the law of evolution existed in the universe, these things would slowly but surely creep upwards on the path of evolution, so part of her duties involved dealing with those particularly dangerous ones.
Anyway, Artemisia had the 'Authority' to affect the Evolution of a being's existential aspects, though there were conditions attached to this.
