Gunnar of Hlidarendi is a prominent and ill-fated protagonist in Njal’s Saga. The saga emphasizes his heroic strength and admirable character. He is fair and even-tempered until he is threatened and pushed to the brink.

Gunnar and Njal are neighbors in southern Iceland, with Gunnar’s farm just north of Njal’s home at Bergthorshvol. They have a strong friendship that is characterized by mutual admiration, respect, and loyalty. However, their friendship is tested on multiple occasions as their wives engage in a brutal feud, resulting in the slayings of various members of their households. Nevertheless, Gunnar and Njal reach reasonable agreements and promise to remain friends.

Gunnar often seeks Njal’s advice on legal and personal matters. Njal is an accomplished lawyer who supports Gunnar at the Althing when he is declared a full outlaw. Njal’s prophetic visions often concern Gunnar, and he warns his friend repeatedly about various matters, including feuding. Gunnar often heeds Njal’s advice, but he finally meets his death when he breaks his settlement and his promise to Njal by refusing to go abroad as an outlaw. Gunnar dies heroically, defending himself alone when he is besieged at home.
