Ender-Marker

The Ender-Marker is a block provided by the Extra Utilities mod. It is used to define the area of effect for an Ender Quarry. As opposed to fences, which require outlining the entire perimeter, Ender-Markers only require being placed on three corners of the perimeter. For this reason, Ender-Markers are often used when constructing large Ender Quarries.
