Quest of the Element Designer

After defeating the Pony of Shadows, Starswirl ?and his newfound legend friends? have one mission to take care of: Starswirl has a lot of immortalized protégés since his disappearance, and he must check up on them, as they guard among his most powerful creations, and while also discovering what his other works have been used for, make sure they and the relics they're guarding are safe from a new threat in the form of an evil goblin named Beezen, a master warlock sorcerer whom Starswirl and later Clover the Clever defeated eons ago, albeit with the use of the Elements of Harmony, who took over Starswirl's castle and all his students by using a paint that could bound all power to him and thus allow him complete control out of whatever it touches, and alter it to his using, and has returned from his prison in Tartarus to complete his plan by tracking down all Starswirl's power, with the help of bumbling goblin witches and his original creation of the Smooze, which was far different than the one Discord was friends with as Smooze didn't want to talk about his family. Thus, with this new G1 villain repurpose on the loose (unless of course given a canon repurpose), the heroes must stop him from doing so.
