Tirek returns, and this time, he's plans ahead of the Princesses and even Discord! He first saps their magic and banishes them to Tartarus. Afterwards, he then goes to steal every ounce of magic he can and rule Equestria with a tyrannical fist.

But there's a slight flaw with his plan. What he doesn't know, is that the Children of Harmony are planning to overthrow and destroy Tirek, once and for all. Will the children be able to stop this evil tyrant or will Tirek intimidate them into a corner?
