The title of the module refers to the five Blades of Corusk, ancient magical swords which, according to the legends of Greyhawk's Suloisebarbarians, can be brought together to be made even more powerful.
The adventure was written by Carl Sargent with cover art by Jeff Starlind and interior art by Ken Frank. It was originally intended as the first of three modules in the "World of Greyhawk Swords" (WGS) trilogy. It therefore precedes the second "Swords" module, WGS2 - Howl from the North. The third module in the series (which would have been coded WGS3) was never produced. Instead, the material originally intended for WGS3 was reworked and incorporated into the board game Greyhawk Wars.
