Guest and Asher grew up very close. Guest is the daughter of Sir Mander. The right hand warrior to the King. So Guest grew up training with Asher and the Knights of the kingdom. When both Asher and Guest were chosen as riders by the dragons is when they realized they were mates. The powers the dragons give their riders helped them recognize their relationship. The dragons bore the riders chose the power they are given, rather it is awakened within them as the great mother says. Guest can manipulate shadows, can make shadows into solid material known as shadonea, and can manipulate the weather. And shadonea is the only material that can cut through Guests skin. No blades other than the ones they conjure up can make them bleed . Asher’s powers consist of mind manipulation and water and earth bending. He can make someone perceive one reality while the true reality is entirely different. And in addition he can make water and the earth do as he wills. He also has healing capabilities through the water bending.
