“Nameless City, Nameless Terrors” concludes this collection with an expedition into the heart of Arabia’s Empty Quarter in search of Irem as described in Lovecraft’s “The Nameless City”. This scenario requires investigators to risk their bodies and their minds as, in the midst of the desolate ruins of Irem, the investigators learn something of the nature of the Great Old Ones, and perhaps forestall the rising of Cthulhu from his watery grave.
