Silence.
We stood in silence. The being that had appeared radiated a presence that made one's mouth dry. It was an aura of pure despair that permeated the air around us, like a cloud of poisonous gas. This feeling, which made all the hairs on my body stand on end, appeared to be shared among our enemies as well since all of them had also stopped in place. They stared in awe at this being that had just appeared upon a white flash of light.
This creature, humanoid in shape and appearance, draped in a black cloak and wearing a pristinely carved mask that was colored purple simply stood up, cracked their neck, and looked around for a moment as the wind slowly blew. None dared interrupt them.
After a few moments, the creature began to speak. Their voice, muffled and shifted by their mask, sounded genderless and without an accent.
