I'll try to find it sometime in the next few days and link it. It had plenty of the princesses and the princes and wasn't overloaded with Nunnally and Lelouch childrens either. Right up your alley.

Since this is the one Lelouch is said to be swiping, I'm still wondering why he learned to pilot a mech in the first place. Is this something they teach all young Britannians, as is when Lelouch lost his status with the Kururugi family as well?
