EveryGach [[Samhain]], '' the phantom [[Aillen]] mac Midgna would terrorise Tara, playing music on his harp that left every warrior helpless. Using a magic spear that rendered him immune to the music, Fionn killed the phantom. As a reward, Fionn was made the leader of the Fianna, replacing Goll, who had to swear fealty to him.

''Fionn was hunting a fawn, but when he caught it, his hounds Bran and Sceolang wouldn't let him kill it, and that night it turned into a beautiful woman, [[Sadhbh]], who had been transformed into a fawn by the druid [[Fear Doirche]]. The spell had been broken by the Dún Allen, Fionn's base, where, as long as she remained within, she was protected from the spell. They were married. Some while later, Fionn went out to repulse some invaders and Sadhbh stayed in the Dún. Fear Doirche impersonated Fionn, tempting Sadhbh out of the Dún, whereupon she immediately became a fawn again. Fionn searched for her, but all he found was a boy, whom he named [[Oisín]], who had been raised by a fawn. Oisín became famous as a bard, but Sadhbh was never seen again.

''One of the most famous stories of the cycle. The High King Cormac mac Airt promises the now aging Fionn his daughter [[Gráinne]] as his bride, but Gráinne falls instead for a young hero of the Fianna, [[Diarmuid Ua Duibne|Diarmaid]], and the pair runs away together with Fionn in pursuit. The lovers are aided by Diarmaid's foster-father, the god [[Aengus]]. Eventually, Fionn makes his peace with the couple. Years later, however, Fionn invites Diarmuid on a boar hunt, and Diarmaid is badly gored by their quarry. Water drunk from Fionn's hands has the power of healing, but when Fionn gathers water, he deliberately lets it run through his fingers before he gets back to Diarmaid. His grandson [[Oscar mac Oisín|Oscar]] threatens him if does not bring water for Diarmaid, but when Fionn finally returns it is too late; Diarmuid has died.

''Between the birth of Oisin and the Battle of Gabhra is the rest of the cycle, which is very long and becomes too complicated for a short summary. Eventually, the High King Cormac dies and his son [[Cairbre Lifechair]] wants to destroy the Fianna because he does not like paying the taxes for protection that the Fianna demanded,. so heHe raises an army with other dissatisfied chiefs and provokes the war by killing Fionn's servant. Goll sides with the king against Clan Bascna at the battle. Some stories say five warriors murdered Fionn at the battle, while others say he died in the battle of the Ford of Brea, killed by Aichlech Mac Dubdrenn. In any case, only twenty warriors survive the battle, including'' Oisín andagus Caílte ina measc.
