I am collaborating with an author named Silver Malice for a story called...

Daring Do and the Sword of Excalibur.

Its about Daring Do and Rainbow Dash trying to find a powerful weapon known as Excalibur before a evil griffin priest and his legion of followers find it to conquer the world. While on the journey, Daring and Rainbow are also trying to rescue Scootaloo from said griffin, as she is connected to finding the sword.
