Not a Star Trek zine, but based on the universe of House of Zeor, a pro publication by Jacqueline Lichtenberg, known in ST fandom for the Kraith series. I did not read any of these - they feature stories, articles & letters by JL and others. The only Star Trek connection seems to be zine ads, con announcements & so forth. The Zeor universe apparently has tentacled people called simes in conflict with others called gens. Here's the biblio information:
