Spyro: Shadow Legacy

At the end of their vacation at Dragon Shores, Spyro and his friends depart back to their homelands before wishing him the best of luck with some magic training at the Dragon Temple. Not long after he falls asleep on the beach prior to going there, a dark storm appears and traps everyone within the Dragon Realms, Avalar and the Forgotten Realms in a strange dimension known as the Shadow Realm. After initial guidance and being granted the Shadowstone, Spyro embarks on an adventure. (wiki)
