The initial Moorcock related release was the BC5 Box in Feb 1986. The EC blisters were released in July through September 1987 to support the Stormbringer RPG that GW were reprinting under license . The EC range appeared in the 1988 catalog, but was discontinued shortly afterwards. The Melnibonean range became High Elves, but the Pan Tangians disappeared.
