If you wake up in a field of green grass, looking at a woman of flesh and steel. Be glad, you are dead. If you wake up covered in blood and shit, be gladder still. For you are alive and your time is not yet come!
Cowardly maggots! Bow your thrice cursed heads and thank the goddess that you still draw unworthy breath!
The ruling family depends on some magical artifact or place to secure their right to rule. A monarch isn't considered legitimate until he or she has been "accepted" by the artifact or place, whatever that might entail. It is also possible that some one else, not of the ruling family, could be accepted as the legitimate heir... A fact which the monarchs would like to keep secret.
