In the night.
On a road, a large troop of soldiers clad in gray armor were swiftly advancing. As they marched, apart from the "swish" of footsteps and the occasional slight clatter of iron armor and weapons, there was no other sound, like a group of phantoms.
At the forefront of the soldiers was a gray-armored knight on horseback. As he was moving, he suddenly sensed something, raised a hand, and the numerous soldiers behind him quickly halted.
A figure drifted down from the night sky ahead, a wizard clad in black robes.
"Clap!"
The wizard landed on the ground, gazing at the gray-armored knight.
"Clatter!"
The soldiers behind the gray-armored knight revealed vigilant expressions, and light emerged on the surface of their battle armor. Spears were raised, infused with energy, ready to be thrown at any moment.
