The energies started intensifying, and I felt each trace of it. They seemed to draw some energy from their bodies, but I sensed especially the use of their souls and mental power to cast these spells and dark magic. It was as if they were drawing energy from the earth and nature's elements. This was different from how sorcerers wielded magic, but I was certain there were overlaps.
I observed each trace of energy, their movements, and the elements they used, along with their unique language and intonation. As time passed, I could sense that the runes and energy in their hands seemed to form vortices. Discreetly, my eyes glowed, charged with Qi and mental power, allowing me to see that what they were doing was beginning to drain the life energy and souls of the others. Indeed, it was dark and cruel magic, even draining innocent lives.
I sighed silently and decided to intervene.
"Excuse me, but I have to stop your actions."
