Magnus is possibly the most gentle being you'll ever meet. His control over the doves proves he is a great leader, since all of them willingly follow him. Their use though, varies through different things. From passing messages, to expressing love... for you.

Whenever he tries to do something romantic, his doves are there to support him. They help set the scene, sometimes they even deliver you gifts from him. His sweetness makes it too hard to reject him, but he would understand if you did.
