The London Inner Circle conspired with Black Air,
the British intelligence agency charged with investigating
the paranormal, to take control of a demon. The Inner
Circle and Black Air intended to use the demon's
mystical energies to take mental control of the people of
the United Kingdom. However, their plan misfired, and
the demon began spreading insanity through the
population of London. The London Inner Circle's Black
Queen killed its Black King when he went mad. Finally,
the British team of superhuman champions Excalibur
succeeded in defeating Mountjoy and Margali and
entrapping the demon. British legal
authorities apparently brought the London Inner Circle
to justice.
In the alternate future eight decades hence from which
the X-Man Bishop comes, the Hellfire Club still exists
and operates in New York City. Its Inner Circle still
secretly consists of superhuman mutants in search of
power, and it is headed by Sebastian Shaw's heir,
Alexander Shaw.
