The events that belong on this tree.
A group of scions rebel against the system, create a major criminal enterprise, and are eventually taken down with prejudice.
Cor is born to Kath (a cardinate) and Leo (a scion) and automatically made an scion. Neither of his parents is permitted to know who he is.
Cor tries to be nice, but he's already under watch by a few bigoted cardinates. He's kidnapped and badly beaten. Other scions rescue him.
