From publisher blurb:
A Sourcebook of Mythic Scotland
Come to a land of hills and shadow, where faeries evil and benign daily touch the lives of the inhabitants. Here, near-immortal magicians change throughout the centuries into hideous monsters, and monoliths tell of ancient battles in tongues spoken only by a few shadowy magi.
Lion of the North includes everything you need to play individual stories or entire sagas set in the Scotland of Mythic Europe. You'll find extensive historical background on the region, new creatures, rules for new magi, and much more.
