Númenórean Ruin

A Númenórean Ruin is a structure found on Middle-Earth Islands. It is the remnant of the great Númenórean empire of the First and Second Age. It is made of stone bricks (regular, cracked, mossy) and cobblestone (regular, mossy). Inside, there is a chance an oak or beech tree will spawn, but it is possible it is empty. There are small, and less common large variants, however the two are indifferent besides in size.
