Ossian
The official narrator (or story-teller) of the saga
The nearly tireless(*) official narrator of the saga.
There are some historians that believe it is the voice of the archaic storyteller who was the first person who passed on the endeavors of this small but legendary Viking company (@VIKBZ) by word of mouth and which were later transcribed to what we have today.
(*) the "nearly" is appropriate at the episode.
