Randolph Carter is an antiquarian and one-time student of Miskatonic University. Based on clues from various sources, he was probably born around 1874 and grew up in and around Boston. At the age of nine, he underwent a mysterious experience at his great-uncle Christopher’s farm and thereafter exhibited a gift of prophecy.
He is the descendant of Sir Randolph Carter, who had studied magic during the reign of Queen Elizabeth I of England. Sir Randolph had then emigrated to America and his son Edmund Carter later had to flee the Salem witch-trials. Carter also had an ancestor involved in one of the Crusades, who was captured by the Muslims and learned “wild secrets” from them.
Randolph Carter is long time friend and colleague of Dr. Weatherby, although no one has seen Randolph for a number of years since his last inquiry into a mysterious incident involving a “silver key”.
