The stories are set in a wooded, Medieval Ireland filled with larger-than-life hunters, warriors, kings, and fairies.

Many stories concern the Fianna and their captain, Fionn mac Uail, from the Fenian Cycle of Irish mythology.

Tuan lost consciousness in a violent storm and woke to find himself transformed into a powerful stag.

To protect Fionn from clann-Morna, his mother sends him to be raised in the forest by two druids, Bovmall and Lia Luachra.

Fionn leaves the poet and attends a Samhain feast at Tara, seat of the High King of Ireland.

As he approaches the fairy, Fiacuil emerges from the forest and offers Fionn his magical spear, with which he will be able to resist the sorcery of Aillen.

Uct Dealv takes the shape of a messenger, approaches Iollan's castle, and indicates that she has a message for Tuiren from Fionn.

After exacting a promise of eternal loyalty from Iollan, Uct Dealv accompanies him to the home of Fergus and changes Tuiren back into a human.

Fergus is heartbroken at losing his dog, so Fionn sends him a new puppy, which quickly cheers him up.

That night, a fairy woman named Saeve enters Fionn's room and begs for his protection from the evil magician Doirche.

His butler explains that a figure who looked like Fionn approached the castle, and Saeve ran out to meet him.

When Becfola attempts to rendezvous with Crimthann, she is misdirected by fairies and ends up lost in the forest.

The next day, at a feast, a cleric is present who witnessed the fight for lordship of the small island.

Goll mac Morna, the most renowned member of clann-Morna, attends a feast with the other Fianna.

Fionn insists that he will not make peace with clann-Morna until the High King has pronounced judgment on the attack.

Fionn decides that the contest shall be a race, and he seeks to locate Caelta mac Ronán, the fastest warrior of the Fianna.

The Carl runs back to retrieve his coattails, then passes Cael again and wins the race.

The Carl hits Cael with a fist full of blackberries, tosses him onto his ship, and sends him back to Thessaly.

Becuma, a woman from the many-colored land beyond Faery, is banished to Ireland for running away from her husband.

Becuma agrees on condition that he send his son away for a year to give her time to learn to love Conn without distraction.

Conn hears a prophecy that he must sacrifice the son of a sinless couple to end the famine.

After a long journey, he locates such a boy: the son of a king and queen on a remote island.

As a penalty, Art instructs her to leave Ireland until she locates the wand of Curoi, a task he hopes will be impossible.

Becuma instructs Art to leave Ireland until he locates Delvcaem, daughter of the magician Morgan.

Art undergoes a long quest full of trials and dangers before finding Delvcaem imprisoned by her parents.

There, they feast and Mongan agrees to tell a story about his past: Eolgarg Mor, the king of Lochlann, is ill. A doctor indicates that only a white cow with red ears can save him.

It is owned by the Black Hag, who only agrees to relinquish when Fiachna promises to replace it with four other cows.

As Fiachna delivers the white cow, he is informed that his father has died and he is the new king of Ulster.

Manannán, the son of Lir, offers to rescue the survivors and help them defeat Eolgarg Mor in return for all the rights of Fiachna's crown and household for one day.

He defeats Eolgarg Mor, becomes king of Lochlann, and repays the Black Hag to her satisfaction.
