Legendary Danish king in the context of "Saxo Grammaticus"

Heorot (Old English 'hart, stag') is a mead-hall and major point of focus in the Anglo-Saxon poem Beowulf. The hall serves as a seat of rule for King Hrothgar, a legendary Danish king. After the monster Grendel slaughters the inhabitants of the hall, the Geatish hero Beowulf defends the royal hall before subsequently defeating him. Later Grendel's mother attacks the inhabitants of the hall, and she too is subsequently defeated by Beowulf.

Halfdan (Old Norse: Halfdan, Old English: Healfdene, Medieval Latin: Haldānus: "half Dane") was a late 5th and early 6th century legendary Danish king of the Scylding (Skjöldung) lineage, the son of king named Fróði in many accounts, noted mainly as the father to the two kings who succeeded him in the rule of Denmark, kings named Hroðgar and Halga in the Old English poem Beowulf and named Hróar and Helgi in Old Norse accounts.

Halga, Helgi, Helghe or Helgo was a legendary Danish king living in the early 6th century. His name would in his own language (Proto-Norse) have been *Hailaga (dedicated to the gods).

Scholars generally agree that he appears in both Anglo-Saxon (Beowulf) and Scandinavian tradition (Norse sagas and Danish chronicles). In both traditions, he was a Scylding, the son of Healfdene and the brother of Hroðgar. In Beowulf, his relationship to Hroðulf is not explained, but if he was not his father, as in the Scandinavian tradition, he was at least his uncle. Both traditions also mention his family's feud with Froda and Ingeld.

Eadgils, Adils, Aðils, Adillus, Aðísl at Uppsölum, Athisl, Athislus or Adhel was a semi-legendary king of Sweden, who is estimated to have lived during the 6th century.

Beowulf and Old Norse sources present him as the son of Ohthere and as belonging to the ruling Yngling (Scylfing) dynasty. These sources also deal with his war against Onela, which he won with foreign assistance: in Beowulf he gained the throne of Sweden by defeating his uncle Onela with Geatish help, and in two Scandinavian sources (Skáldskaparmál and Skjöldunga saga), he is also helped to defeat Onela in the Battle on the Ice of Lake Vänern, but with Danish help. However, Scandinavian sources mostly deal with his interaction with the legendary Danish king Hrólfr Kraki (Hroðulf), and Eadgils is mostly presented in a negative light as a rich and greedy king. Snorri Sturluson, who documented many of the Scandinavian traditions, reported that the Swedes called him a "great king".
