Earthdawn: The Age of Legend - Familiars
Adepts rarely face the dangers of Barsaive alone. In addition to their adventuring group, many adepts surround themselves with loyal animal companions. Known as familiars, these creatures share a strong bond with their master—almost similar to the one between a Cavalryman and his mount. Those ties are sealed with a familiar oath and infuse the familiar with the adept's magic and other special abilities. Familiars are most common with Beastmaster and Magician characters but may serve adepts of any Discipline.
