Randolph Carter, who had all his life sought to escape from the tedium and limitations of waking reality in the beckoning vistas of dreams and fabled avenues of other dimensions, disappeared from the sight of man on the seventh of October, 1928, at the age of fifty-four. His career had been a strange and lonely one, and there were those who inferred from his curious novels many episodes more bizarre than any in his recorded history. His association with Harley Warren, the South Carolina mystic whose studies in the primal Naacal language of the Himalayan priests had led to such outrageous conclusions, had been close. Indeed, it was he who - one mist-mad, terrible night in an ancient graveyard - had seen Warren descend into a dank and nitrous vault, never to emerge. Carter lived in Boston, but it was from the wild, haunted hills behind hoary and witch-accursed Arkham that all his forebears had come. And it was amid these ancient, cryptically brooding hills that he had ultimately vanished.
