Keith Herber of Chaosium noticed this first issue and helped Tynes recruit Cthulhu writers including Scott David Aniolowski and Kevin Ross.

Varney praised the magazine's articles as "Fascinating features, columns, letters, and huge amounts of period source material (which is sorely lacking in Chaosium's own support for CoC)."
