Terraria: Calamity in the Mortal World

In the year 2060 of Blue Star history, a mysterious force descended, and disaster struck. Vast mineral deposits appeared beneath Blue Star, monsters from games and creatures no one had ever seen emerged across the world, and the power of the gods drove people to despair! There are even beings in the cosmos that prey on so-called gods!

"Gods do not fear death!"

"So what if you're a god? I'll cut you down and show you!"

[This story takes place in the real world. You can enjoy it even if you've never played Terraria; it simply borrows various items and monsters from the game.]
