Dr. Vortex and his Trustees of Hate operated from a castle hidden in the Balkans. There they constructed a Death Ray which Vortex had hoped to use against the neighbouring nations of Gratzia and Borisa. Their operations were destroyed and the Trustees slain by the undead hero known as the Blue Blaze
During a period in which they believed that their powers were fading Quicksilver and the Scarlet Witch visited a small village nestling in a peaceful Balkan valley where they believed being closer to their place of birth could restore their powers. There they realised how badly they liked being Avengers.
