Camilla's past has come back to haunt her in the form of
Taisgeal, a celtic fox seeking her in the guise of her previous name of Xin Jin Meng, the New Gold Dream. It seems the dragoness is the Unmaker, a powerful weapon accidently given sapience in a political conflict on a planet in the farther reaches of Puzzlebox.
In the Mess, where destructive powers are compensated for or simply abolished, she poses little immediate threat in of herself to anyone (despite being responsible for a small yield atomic blast in Upwarp in a fit of pique -- she is sorry about that). However, if she were forced to return home, she might kill many people.
Taisgeal's people, on the other side of this conflict, do not want to risk that possibility. He has been sent to eliminate her.
The only problem is that others have caught wind of this and have devised a crafty plan to deal multiple issues concerning Camilla, Taisgeal, and Jeremy.
The leading conspirators appear to be System and Mel.
