A few weeks after their Christmas and New Year adventures, the Mane 6 are sent on another Unity Quest that reunites them with Mystery Inc and a foe from their not-so-distant past.

An evil sorceress, Morgan le Fay, has teamed up with Opaline Arcana (who Paradise brought back near the end of the last adventure without the ponies knowing) to take over Camelot and seize some cutie marks so Opaline could take control of all magic, in Equestria and in other worlds, so King Arthur and some brand-new friends need the help of our favorite supersleuths to save their home.

But will their valiant efforts only make things royally worse? Will Paradise finally see the error of her ways and join her daughter on the side of right? Will the Mane 6 and their friends finally defeat Opaline, even with the evil alicorn stealing their cutie marks to fuel her own powers?!

This epic adventure serves up laughter on a platter and should teach all that courage and hope are the strongest weapons of all!
