From the introduction:
Aw hello Portal Master! Welcome to Skylands: a magical world of wonder and adventure, ruled by the greatest heroic emperor ever known – ME! HAHAHAHAHA! For centuries, meddling do-gooder Portal Masters like you have been sending their miserable Skylanders to stop ME, and hold back the gloriously evil power of The Darkness! But NO MORE! Because now, the Portals are under the complete and utter control of, BUN-BUN-BA, ME, KAOS! And in case you foolish human fools haven’t figured it out yet, I’m the bad guy! HAHAHAHAHA! Glorious, isn’t it? But wait, there’s more. Because I’ve taken the opportunity to capture anyone in Skylands who could’ve even remotely, possibly, helped you. Anyhoo, now that I control the Portals, I am cutting you off from Skylands, FOR GOOD! With no more Skylands to go back to, your Skylanders will simply be the helpless toys I’ve always known them to be. So long, Poser Master, FOREVER! HAHAHAHAHA!
