The excerpt describes the plight of Hrothgar, the king of the Danes, as he and his warriors suffer at the hands of the monstrous Grendel. Grendel, a descendant of Cain, emerges from the darkness to attack the mead hall of Heorot, slaughtering thirty men in his first assault. The joy of Hrothgar’s warriors is shattered as they succumb to fear and despair, with the hall left empty for twelve years due to Grendel's relentless attacks. The text highlights Hrothgar's mourning for his fallen friends, as he realizes that "some demon had torn His followers apart." In a desperate attempt to find solutions, Hrothgar and his council seek guidance from pagan gods, sacrificing to "the old stone gods" in hopes of driving off their curse.
Grendel’s reign of terror features prominently, as he hunts his prey with impatience and delight, embodying the embodiment of evil: "the only survivors Were those who fled him." Grendel’s assaults not only wreak havoc but also deepen the sorrow of Hrothgar, leading to a collective anxiety within the kingdom as they face a seemingly insurmountable threat. The narrative stresses the futility of their efforts, given their ignorance of the Christian God: "their ears could not hear His praise nor know His glory." The passage concludes by warning those caught in despair without hope: "Let them Beware, those who are thrust into danger."
