Barrow (Thaumcraft 6)

A Barrow is a landmark added by Thaumcraft 6. They can be found scattered throughout the world, in any biome.

The exterior of a barrow is a small 5-block high hill with an entrance made of cobblestone and chiseled stone, and iron bars blocking the entrance. Inside is an unlit 3-story structure made entirely out of cobblestone and mossy cobblestone, with a hole in the middle. A staircase on the end opposite of the entrance leads down to the first basement level, which hosts a skeleton spawner and a zombie spawner, and a ladder down to the bottom of the hole in the center of the structure.

In the hole spawns a chest (which may be trapped with TNT) filled with simple dungeon loot, and two of either urns or crates.

Trivia

 * A barrow is an ancient burial mound. "Barrow" has roots in the German and Dutch word "berg," which means "hill" or "mountain."
 * In earlier versions of Thaumcraft, barrows also hosted dark nodes.
