Lemme get cracking on rewriting the Lannister sheet here so we have a sense of what happened during the Dance of Dragons (since I diverge a bit with a split between Lannisters on which side to take). I left the Reynes intentionally unnamed/undeveloped out of the sense that someone might want to play them. ;)

I'm working on setting it up as more dissension in House Lannister during the Dance, since there were a Marbrand and some others that went black. I'll have the history ironed out -- I'm just trying to keep it straight with the "Princess and the Queen."
