Namulis

"The Emperor, Older Brother" of Dorok. He doesn't have a mystic power, and had been virtually locked up in the palace for 100 years. Near the end of the story, however, he leaves the capital, Shuwa, and starts taking charge of things. 100 years of boredom seems to have affected his psyche rather badly, and now he wants to have some "excitement", which is a bad news for Nausicaä and everyone else.
