Once they started casting spells, it made it a bit easier to identify them.
After all, the magic that they cast…was very similar to the magic that Moon and her elves were using.
It was clear that the other side was either composed of elves or they were related to the elves in some way.
But these spells didn't do anything to Cecilia and Moon's group.
The arrows and swords that they used were made of mithril, which was very sensitive to magic. Not only was it easy to infuse magic into mithril, mithril could also be used to cut right through magic energy.
So they were able to easily dispel all of the spells thrown at them while still putting pressure on the cloaked figures.
The cloaked figures saw that their spells weren't working, so they did the only thing that they could do. They turned around and wanted to run away, but they found that a few of the knights had already circled around and cut them off.
