You can download the Wherigo cartridge here: Necronomicon Ex Mortis
This Wherigo cache is homage to the 1981 cult-hit horror film, Evil Dead, where five friends become holed up in a remote cabin. They find a tome called the "Necronomicon" and a taped translation of the text. Once the tape is played, they unwittingly summon dormant demons living in the nearby woods, which possess them in succession until only one is left intact to fight for survival.
To find the cache, you must first follow the instructions found at the start location.
A warning - the original Sumerian text, incantations and engravings have been used as part of this cache experience. As a result, it is not recommended for children.
Most importantly DO NOT ALLOW ANYONE TO READ FROM THE BOOK!
