Ok. I'm gonna enter into this. Hopefully I'll get internet and finish this before the deadline.
The Tale of the SpiritsOh! I didn't see you there! Welcome, welcome, to the great Library of Terraria! Not many people come here, you're the first in a couple days. We just got in a new book, detailing the legend of the Spirits of Light and Dark. Since you're here, I'll give you a deal. I'll read it for you.
Once upon a time, there were two spirits. Light and Dark, Day and Night, Good and Evil. They created Terraria, and balanced each other out. But the Darkness became overcome with greed, and created dark armies to take over Terraria. The Light saw this, and fought back. The world became a bloody battleground. Seeing an opportunity, the Darkness took over the flesh and fused it with the world, creating a second army. The Light was overtaken, and it knew the only way to save Terraria was to seal the Darkness away. But the only way to do this and keep the balance of the world would be to seal itself away as well. So the Light sealed both away and created a gatekeeper of sorts, the man we know as the Guide. He would search for a person who was capable of returning peace to the world, and give them a test of strength. But after so many years, the seal began to waver, and the darkness seeped through. The armies began to regain strength, and created leaders, a titanic worm and a monstrous brain. Meanwhile, the darkness was using the little power it had regained to corrupt the Light itself. The world needed a hero soon. The Guide had yet to find one worthy of releasing the Spirits.
