I am a Light Idol. It seems you know my purpose. I will go with you.
Worshipers of light gave this miraculous stone idol life through prayer. It's said that the holy power it holds can call forth mysterious powers sleeping in all life. Its discoverer was attracted to its divinity, got too close and then took a severe blow from it. It's called the "light-beard giant" since beams of light are seen emitting from its mouth.
