Polyhedron (Issue 23 - Vol. 5, No. 2)

Cover art: This month's cover is a Tom Wham original, created especially for our April Fool issue. The scene depicts critters from the various Foolish articles in these pages - gargoyles (with and without wings), a flying slime, a man and his frog, and of course some snits and a confused bolotomus in the foreground. (from the contents page)

This was the annual April Fool's issue, featuring almost a dozen articles proving there is room for levity in gaming.
The only serious feature was In the Black Hours, Part 2 by David Cook, an adventure that was used as a sponsored tournament at GEN CON South 1984 Game Fair and at CONTACT 1984 convention.
