Just as the battle on the city walls fell into a stalemate, a piercing screech suddenly filled the sky, forcing the archers in the watchtower to cover their ears.
"Flomos!" As the screeching ended, the soldiers heard the herald's roar, "Watch your heads! Archers! Intercept them!"
A flock of what seemed like crows approached from the sky, growing rapidly larger as they neared. These flying demons had gigantic black wings, humanoid body structures, and vulture-like talons, coupled with an unbearable loud squawking.
The archers in the watchtower immediately shifted their aim, as these airborne demons posed a greater threat. Bereft of the supportive fire from above, the warriors grappling in close combat on the walls suddenly felt the pressure mount, as the enemy ascended the ramparts at a much faster speed, but the defenders found it difficult to increase their rate of killing.
