The first issue was published in the Spring of 1977 in Vancouver, British Columbia, Canada, where all four editors were members of the British Columbia Science Fiction Association and Allyn was editor of BCSFAzine.

L. Petard, "Tidepool" by Susan Wood, a 2-page comic collaboration between Ken Fletcher (Rune) and William Gibson, and an editorial called "Dangerously Amateur" by Allyn and William.

In its pages, Marta Randall writes about a music festival; Doug Barbour reviews two novels by Michael Bishop; Bill Beard reviews Star Wars and Rabid; Susan Wood writes about John Bangsund, editor of Scythrop; and John Bangsund writes "John W.
