My favourite character for each book has died in that same book.

These are my favourite characters as I was readin GB through each book.

Red Rising: Pax au Telemanus

Golden Son: Fitchner

Morning Star: Ragnar (Sevro was a close second, and he had a fake death)

Iron Gold: Romulus au Raa

Dark Age: Alexandar

Lightbringer: Cassius

As of right now, my favourite living character is Diomedes, which does not bode well for me reading Red God.
