When did she get to be a beauty?
When did he get to be so tall?
Wasn't it yesterday
When they were small?

Sunrise, sunset
Sunrise, sunset
Swiftly flow the days

Dusk, the elder of the two siblings is intense, emotionless, a bit gloomy and kind of creepy to be in the presence of. He seems to be able to suddenly be right behind you when you least expect it which can be quite the shocking experience.

He may not show his emotions on the surface, but he cares deeply for his sister Dawn. As far as he is concerned the most important thing in the world is keeping her happy and bubbly, even if it does mean he occasionally gets goo through his fur from one of her hugs. If you ever manage to upset Dawn, you will never see Dusk coming until it is too late, so don't upset Dawn.

Sister: Dawn
