In the binary (good vs. evil) epic world of Beowulf, the king is a defender of law and order, and Grendel is the villain who challenges these principles. But neither the king nor Grendel act on their own. The king is God's representative on Earth and a protector of all his subjects. On the other hand, Grendel is not an ordinary villain or a monster. He is the descendant of Cain, Biblical figure who killed his own brother. As a creature of hell, he mustn't touch the king's throne, which is God's endowment. In other words, the one who symbolizes the Devil must stay away from God's symbols.
I think you mean a scaler quantity.
a scaler quantity is something that is measured without a directional component to it.
ie. mass, temperature, speed
it could be negative value but the negative means its value. you can use a scale to measure scaler quantity.
