It has a Norse? storyline, but it's basically just killing monsters (and buying/selling stuff to kill them with, or keep from getting killed.)
In 1998, the author [Rick Saada]? decided to make it public domain and released the registered version for free, which can now be downloaded at the only substantial cotw website: http://cotwrpg.cjb.net/
Suprising, because Rick Saada is a former Microsoft employee.
