Spike had given up on dragons, considering them all to be delinquants after he met with some of them during the great dragon migration.
But one night after getting into an argument with his friend Twilight, he began to have strange dreams where a strange being would talk to him claiming to be a dragon spirit of a long lost race of dragons with beyond extraordinary power and that Spike himself may be one.
Now Spike is in danger from the very Ponies he called his friends and may even re-awaken a war without end, the eternity war is threatening to return and Spike is the only dragon with the power to stop it.
