"Massive monster claw made of blackstone, deepslate, and basalt, with 4 curved sharp talons rising from the sea like fingers reaching up. Base is jagged, burnt, and charred with lava pools and embers around it — rocky terrain, NOT a smooth volcano cone or crater. Inside the claw is a hidden hollow chamber (not visible from outside, not an open top) containing a multi-level iron farm. Huge, imposing scale, standalone in open sea."
