Four Origins Tournament Adventures
This book presents the Shoggoth.net Group's four Origins 2005 tournament adventures. Each scenario features one of man-kind's futile struggles against the Masks of Nyarlathotep and other powerful creatures of the Cthulhu Mythos. This monograph is intended for a mature audience.
The first scenario, 'Where Byakhees Dare' takes veteran British solders, on a special operation, into the heart of Castle Straussberg in World War II Switzerland.
The second scenario, 'Reborn To Die' takes modern day students on a search for a Miskatonic University Professor through Lovecraft Country.
The third scenario, 'Funk-A-thulhu' has a group of 1970's investigators inquiring into the strange events surrounding the death of Sweet Suzie, a prostitute in Los Angeles.
And finally, the fourth scenario, 'Crazy Block' pits the insane, convicted and incarcerated criminals of Private Correctional Institution Wayfold against terrible modern day agents of the Cthulhu Mythos.
