Chain Challenge is a young stallion from Canterlot.
He is fairly well-known as an escape artist and magician, performing at least once a week. Although one might guess that he could cheat to escape by using his magic, he always adds an extra challenge by having his assistant, Willow LaWisp (Sphie's OC), put a magic lock spell on his horn while performing. As a magician he is known for his skill with his phantom spell, which some unicorns can do but few to his extent.
