DUN DUN DUNNNNNN TO EVERYTHING

I made no real foreshadowing that there is a Caesar, so don't go looking for it. I'm not lying, promise.
Zen, however, I did sort of foreshadow Zen's lineage being important. There had to be a reason he was so strong and sure of himself. Also why he hated the Legion so damn much.
So, he's the son of the most important zebra in the entire wasteland. Meaning, he's in line to be Caesar. Maybe there are other reasons he left?
