Hamingjar (sing. hamingja) are luck spirits, sent by the gods to reward mortals. Rather than taking the Fortune Glory reward as written, a hero may instead choose to be rewarded with a hamingja. Note this as “Hamingja Fortune” on the character sheet. The outcome is the same for the hero, in that he gains a benny.
However, a hamingja may be loaned to another person. This requires an action from the hero and must be done completely willingly (so you cannot use puppet to force a character to loan you his hamingja). In essence, instead of receiving a personal benny, the character now has one he can share with his comrades.
Furthermore, hamingja can be passed down through generations. A hero may, at any time prior to his death, bequeath his hamingja to a living blood relative) and only a living blood relative) as a free action. The new host need not meet the Glory requirement for this to happen. This allows a new character to begin with an extra benny due to his relative’s heroic actions. The original hero now loses control of the spirit and may never take it back under his command (though he may be loaned it).
No hero may have more than one hamingja under any circumstances, regardless of his Glory or ancestral favors.
