The Shadow of Alfheim 3

As they heard the explanation inwardly, El was heartbroken, removing the fact she immediately wanted to murder this codenamed Eve and Samael. She couldn't accept the fact that Cain was not her fated. In anguish, she decided that her newest skill [Red Strings of Fate] would be her declaration to the world that she belongs only to Arthur. Using her knowledge, she changed the spell words to one that showcased her vow.

When the spell activated, the vision of everyone present turned black, and in its place, they saw the hollow blue outlines of other beings. The outlines were the spiritual bodies of the people around them, the so-called soul. Everyone could see a bright red cord between the pairs of Cain and El and Mu and Joshua.

The others had half a cord in their chests with the other ends not visible; these looked like red scarves. There were also different colors, but what shocked the elves the most was when they looked at Marduk and his men.
