Does this make sense to anyone?
Sagas are a form of lore-keeping and tale-telling common in Irrisen and the Lands of the Linnorm Kings. Specialized applications of a skald’s raging song ability, sagas function much like bardic masterpieces (Pathfinder RPG Ultimate Magic 21) but are available only to skalds. Sagas are never purely artistic constructs; they are designed to preserve lore or commemorate historical figures, and are usually based in fact. Sagas therefore require ranks in Knowledge (history) as a prerequisite, as well. Bards can learn sagas, using their bardic performance ability instead of raging song.
nice. gotta love the soft covers. :/
