10 Crystal Picard, Cardcaptor » by WitchSorceress49 Children don't have adventures, don't really face danger, but when Crystal Picard opens the Clow book, unleashing the most powerful creation of Clow Reed, she finds herself on the path to become the most powerful sorceress, and Mistress of the Clow Book ever. Why? Because Clow Reed saw her before he died. Crossover of Cardcaptor Sakura, but no Sakura.
