The Claws of Ifrinn

From publisher blurb: From the subterranean caverns of the planet Ifrinn comes a menace that seems out of the ordinary, even for the seasoned star-hopping heroes. Engaging in battle with creatures that appear in the world’s history only as legend seems hopeless, especially when there are thousands of them, and they don’t have to touch their victims to harm them. Can the adventurers help the colonists overcome the threat, or will the monsters add the surface of the planet to their hunting grounds? The Claws of Ifrinn is a short adventure for 2D6 science fiction RPGs such as Cepheus Engine, Cepheus Deluxe, and the Original Science Fiction Roleplaying Game. Other 2D6 systems are easily adapted.
