On his way to the White Castle
The fighter hears voices, an eco of nonsense. They say, "stop exploring there's nothing to live for" but he keeps walking to the battlefield.
His fragile body is preparing to die,
Knowing campers are ready to fight, he puts on his mask, his metal armor and indifference to protect his heart.
The battlefield is empty
Nothing to fight, disappointment invades his confidence, because there's no campers to invade his life.
He lost all hope
His heart for once broke. He said "once there's no fight, there's nothing to live for" and his body turned to stone.
