Finn's father Cumhail, a Fianna
chieftain, was mortally wounded and killed in battle by Goal mac
Morn, the leader of a rival clan, before Finn's birth.
Terrified for her new baby's
survival, Finn's mother sent him away intrusting him to two of her
closest colleagues - a druidess named Bodbal and a woman warrior
named Fiachel.
Together these women successfully
raised Finn in secret hidden deep within the mountains of Erinn
(Ireland). During this time they taught him all the lessons and
skills he would need to survive he set out to avenge his father's
murder.
When it was time Finn ventured out
and served under several kings who immediately sent him away, in
fear of a retaliation from mac Morna, after they discovered who he
was.
Discouraged, Finn wandered
throughout Ireland until he met an old poet living near the river
Boyne whom he ended up studying under for seven years.
At the end of these seven years
Finn fulfilled a prophecy when he ate the Salmon of Knowledge and
gained the wisdom he would need to challenge mac Morna.
Gathering 150 of the bravest and
best of the Fianna, Finn sought revenge on Goll mac Morna. The
battle was long, lasting a few days, but in the end mac Morna's
men were no match for the Fianna and Goll mac Morna died on Finn's
sword.
