Donald rejoins the team and they fight a succession of old foes and get help from old friends on their way down to the Summoning Chamber to stop Felldrake's Monstrous transformation. Felldrake billows into the sky in a menacing cloud of darkness forming a demented demon-goose! The Caballeros attempt to use the amulets to force Felldrake back into his staff, but Sheldgoose halts the process by BREAKING the staff. Felldrake, seemingly defeated, is cast into the great unknown. Sheldgoose is kicked out of the Institute. The Caballeros gain possession of Sheldgoose Manor. Sheldgoose shows his eyes burning with dark energy. Felldrake has fled into the body of his ancestor and now inhabits Sheldgoose himself!
