Somebody with SUPER MAGICAL POWERS who is AWESOME just like Healthy-Orphan herself! Except wizards know more stuff because they go to SCHOOL, and are also (in her experience) WEAKER AND LESS AWESOME than ORPHAN, who can SET PEOPLE ON FIRE WITHOUT HAVING LEARNED ANYTHING ABOUT HOW.
The Bleak Emperor is said to be much scarier than the sort of wizards that Orphan used to crush without thinking about it, though. Scary enough to rule the entire Empire. Orphan feels on a deep sense she never thought to think about in words that Orphan herself cannot possibly be THAT scary or awesome.
