A lightning bolt strikes a temple and sends many objects in different directions. A ninja who fights for good falls out of a plane onto this island but everything is in darkness. he emerges out of the shadows blacked out with red eyes. Meanwhile in the Dragon Temple, Tomas is discussing this with other elders:
Tomas: Why is everything dark?
Astor: remember the *wink wink*
Tomas: The shadowstones?
Hunter:Shadowstones?
Tomas: yes great Darkness controllers. They live in a place called Shadowstone Temple, there's 50 scattered throughout the temple. But once they are lost they cant control our darkness so we now have Eternal Darkness until we collect the Shadowstones. The more we collect the brighter it becomes
Spyro: Well who should go? Ummmm yeah
Somewhere far away on a mountain
Crush: Sorry boss but we're the boss now
Ripto#: Im your master! I gave you your power!
Gulp:*stomp*
Ripto: Okay, okay I'll go

Ripto: Please dragons can i join you?
Spyro: Oh dear lord
Hunter: Hey short stuff you've been our nemesis for ages
Ripto: But Crush and Gulp kicked me out from MY gang!

Tomas: Ripto! Be-gone!*puff*
Spyro: C'mon Hunter let's get the shadowstones
