THANK YOU!! I'm so glad you enjoy them!! Honestly, I don't really think so? I'll probably end up wrong, but for me the purpose of the Princess Glow was to objectify Malleus' egg before he was born. Taking Malleus' egg for the Silver Owl's was essentially no different from taking the Princess Glow from Maleanor as a stolen war prize. They put the life of an innocent fae who hasn't even been born yet on the same level as what is basically a magical tool, and both were only wanted as a decoration. That being said, I'll be very pleasantly surprised if it does come back at something important to the story down the road!
