Thank you, both. njc, AJCIII is the POV character. I've read more than once that it's best to establish that in the first sentence, even the first word, if possible. Not sure how important that rule it is.
Janet, yours is very close, but I also need to establish that the illegitimate kids are sons of the emperor, not the empress.
I'll play with both your suggestions. Damn am I bad at this.
Gracias.
