Can anyone tell me where the Tick-Tock Men - from the 'Lost Knowledge' Rumour Mythos Card - come from, and if they are an original creation purely for Eldritch Horror, for Arkham Horror, or are actually from a real story. The only reference I could find are Harlon Ellison's " 'Repent, Harliquen' said the Ticktockman' or, more likely, a form of Nyarlathotep known as the Tick Tock Man, singular, who appears to subvert any technologically advanced civilization. Apparently he does not need to be in a human form, and usually comes around circa the dawn of their Atomic Age.
If anyone has any theories or answers, please post.
