The promise that breaks a province
Fergus serves as a trusted guarantor for the sons of Uisnech, but a feast arranged through Conchobar keeps him from accompanying them to Emain. His son attempts to protect Naoise and dies with him. Fergus retaliates and leaves Ulster with followers. His exile is thus attached to a failed protection whose consequences extend beyond his own wounded reputation.

A heroic name does not assure victory
In the Flidais raid Fergus seeks cattle to support his company, but her husband reads the visit through rumors of her desire. Combat follows, and Fergus is among the men defeated and tended inside the enemy stronghold. The recovery requires a larger force from Connacht. His renown attracts Flidais, yet cannot keep him from needing her care and other rulers' intervention.

The household behind the warrior
After the conquest, Flidais and her herd sustain Fergus and the projected army. The closing notice emphasizes how much his household loses at her death. He later returns to Connacht and dies through Ailill's jealousy. These episodes make resources, care, and political shelter essential to the warrior's life, challenging a reading in which physical prowess makes him independent of everyone else.
