UNCANNY X-MEN (1963) #-1 (VF)

Flashback! In the years before the formation of the X-Men, the highest echelons of the government discover the existence of mutants -- a race they fear threatens mankind's survival! Thus begins the Sentinel program, leading to the construction of Master Mold. But a malevolent force from the future wants to use Master Mold for its own purpose, and only Rachel Summers, the Mother Askani, has the power to stop it! What connection does this chain of events have to the long-fabled "Twelve"?
