It has a house with two floors and a basement, a small pond and a small cave. Inside the cave are two small bodies of water, a couple of pots, ore veins and a Life Crystal.
I built it because I figured it would be a fun project, and because the recently released Sonic set inspired me to make something based on other games, and Terraria seemed like a perfect fit for a lego model.
I think this concept would make for a great display for fans of Terraria, as well as a conversation starter for people who aren't familiar with the game.
