Beowulf

"Would that the stalwart warrior-king's sword offered similar protection."

- Lore

A legendary Geatish warrior who accomplished seemingly impossible victories in life.

Scandinavian Mythology
Beowulf falls into two parts. It opens in Denmark, where King Hrothgar’s splendid mead hall, Heorot, has been ravaged for 12 years by nightly visits from an evil monster, Grendel, who carries off Hrothgar’s warriors and devours them. Unexpectedly, young Beowulf, a prince of the Geats of southern Sweden, arrives with a small band of retainers and offers to cleanse Heorot of its monster. Hrothgar is astonished at the little-known hero’s daring but welcomes him, and, after an evening of feasting, much courtesy, and some discourtesy, the king retires, leaving Beowulf in charge. During the night Grendel comes from the moors, tears open the heavy doors, and devours one of the sleeping Geats. He then grapples with Beowulf, whose powerful grip he cannot escape. He wrenches himself free, tearing off his arm, and leaves, mortally wounded.

The next day is one of rejoicing in Heorot. But at night as the warriors sleep, Grendel’s mother comes to avenge her son, killing one of Hrothgar’s men. In the morning Beowulf seeks her out in her cave at the bottom of a mere and kills her. He cuts the head from Grendel’s corpse and returns to Heorot. The Danes rejoice once more. Hrothgar makes a farewell speech about the character of the true hero, as Beowulf, enriched with honours and princely gifts, returns home to King Hygelac of the Geats.

The second part passes rapidly over King Hygelac’s subsequent death in a battle (of historical record), the death of his son, and Beowulf’s succession to the kingship and his peaceful rule of 50 years. But now a fire-breathing dragon ravages his land and the doughty but aging Beowulf engages it. The fight is long and terrible and a painful contrast to the battles of his youth. Painful, too, is the desertion of his retainers except for his young kinsman Wiglaf. Beowulf kills the dragon but is mortally wounded. The poem ends with his funeral rites and a lament.

Hades
Though Beowulf himself doesn't physically appear in the game, his legendary weapon the Aegis is seen and can be used by Zagreus. Beowulf is implied to not be alive yet, as the weapon is deemed by the fates to have a future purpose.
