Grendel was unable to seize more men due to the protective power surrounding Heorot, the great hall where the warriors gathered to feast and celebrate. This power was created by the Danish king Hrothgar through divine intervention, making it inaccessible to Grendel.
Grendel is about to meet his fate.
In Beowulf, the significance is that Grendel will soon meet his fate.
Grendel eats 30 men. According to Beowulf, Grendel eats only one man.
The men were sleeping after celebrating in the Mead Hall. Grendel attacked them while they were unaware and defenseless, resulting in a horrific massacre.
He takes Grendel's head and swims back to his men, four men carry it back. then Beowulf began boasting about how he killed her. He then becomes king and lives peacefully for fifty more years.
These lines are foreshadowing that the character will not be able to harm any more people after that specific evening due to fate or destiny (Wyrd). This suggests a potential turning point or consequence for the character's actions.
Grendel killed 30 men the first night he attacked Heorot Hall.
Grendel killed one of Beowulf's men before trying to attack Beowulf himself. He suprised Grendel with a strong choke-hold. While fighting, they damaged the mead-hall extensively and Beowulf pulled Grendel's arm from his socket. The arm acted as another trophy for the mead-hall. Grendel killed many more of Hrothgar's men.
Grendel is able to kill 30 of Beowulf's men in the mead-hall, Heorot.
The first verbal exchange between Unferth and Grendel
Grendel completely changes the themes of the story Beowulf. In Beowulf, Grendel is a purely evil monster, the descendant of Cain, cursed for eternity. He kills entirely out of evil. However, in the text Grendel, Grendel suddenly has a reason for killing. He often observes various mead halls in Denmark and watches as men threaten to burn the mead halls of a neighboring kingdom, to steal their treasure and their women. He thinks these to be the empty threats of drunken men, but when he actually sees the mead halls burning, his disposition changes. He is no longer amused but instead disgusted at the waste of men. Although he is a murderous monster, he kills for food, for survival, for reason. He believes men to be destructive and unrelenting, threatening and wasteful. Men burn the halls but leave the people within the hall dead, blackended, and shriveled. When Grendel kills men, he eats them. When these men kill other men, they just leave them to waste away. Suddenly the reader feels sorry for Grendel, understands Grendel's side... Grendel has a personality, he speaks, he has a mother who loves him and who avenges his death. He is suddenly a much more human character and much more relateable to the average reader, whereas in Beowulf he is an evil monster that deserves to die. The whole plot is different. In Beowulf, Hrothgar's men are the victims, Grendel is the evil murderer, and Beowulf is the hero. In Grendel, Hrothgar's men are evil, Grendel is the victim and maybe even the hero, and Beowulf is the murderer.
