Darius really wanted to be right about his thoughts. He really wished that his little boy was just sad that another one was leaving them on a supposed happy day. It's just that he was summoned to the Infirmary Hall to hear about a grim decision that another person had made.
It seemed that Julian… wanted to surrender his portion of Nicholai's power back to the owner. This would cause his body to lose the very thing that had been keeping it from growing old… and dying. Just like the whispers in Darius's mind, Julian was so ready to go with his mate.
Five hundred years was already too old for a non-royal werewolf like Julian, and living after losing his mate didn't sound attractive to him anymore. He was not Enzo who had a crown to succeed or Gilbert Gillard who had pups to raise. He was just a sworn brother of the Rogue King and a servant that had given his body and soul to his liege.
