Lying on the ground full of dead bodies, Lucas was breathing rapidly. The tiredness was showing up in his eyes while he was slowly drowning in the darkness of his own guilt.
He held the sword in his hand tightly and covered his eyes with his left hand. Two lines of tears fall down from two different sides and he murmured "Why did you leave me, brother? I feel so lonely without you."

"Ahhhhhhh!"
