The world of Terraria, where Corruption and Evil spreads from the corner of the world, you had recently arrived here for unknown reasons. You looked around, and saw a massive scenery of Trees, mountains, plains, bunnies, and many more.
But when you looked to your right, you saw a brown-haired fellow with a white shirt, looking at you.
"Why, hello there Terrarian!" He approached, with a smile. "They say there is a person who will tell you how to survive in this land... oh wait, that's me."
You then began to chop trees, because that's the first thing you do in games like these, before Luke the Guide spoke up as you continued to chop trees. "You can use your pickaxe to dig through dirt, and your axe to chop down trees. And if you want to survive, you will need to create weapons and shelter. Start by chopping down trees and gathering wood!" Which you were already doing.
"My name is Luke, I am your guide for the journey ahead in Terraria!" He then points towards an open space. "You should make a house for people to live in to create a town! After all, the more the merrier! Try making a house and making me move inside."
