The Egadingfly

From publisher blurb: Just another horrific critter you can terrorize your players with! The egadingfly is a large fly-like creature that uses human (and humanoid) hosts to breed their young, can control minds, and delights in causing misery and strife. Gamemasters, take the egadingfly out for a spin and tear up some villages with them, give your players AND their characters nightmares they'll never quite shake-- or that's the hope, at least. This PDF provides a dozen pages of gloriously system-neutral material, with some "generic stats" thrown in for a kind of a rules barometer. This offering is also extensively bookmarked, so you can jump from section to section and chart to chart with ease. And there are charts... tables for you to roll on for all kinds of nasty goodies.
