The legendary mask belonging to the great warrior Wyvern has been used in the past to save the land now known as Equestria from eternal darkness. The mask held special powers that not even Starswirl the Bearded could hold. Now, the mask that was once legendary, now lays on the face of a pegasus stallion named Starsky.

But when a dark force has now risen from the depths of Tartarus to retrieve the mask to use the power for itself, it leaves the land of Equestria- and possibly the universe- in mortal danger.

However, Starsky won't let this happen.
