A profound fantasy art of an underwater scene with a giant tree made of ancient machinery that has its roots on the deep sea floor shrouded in darkness. A gigantic tree made from ancient machinery, with many small lights shining on its branches and leaves in the darkness. A group of mechanical ruins from a long-lost civilization that exudes eeriness, broken mechanical tower ruins, shattered remains of an unknown reactor, and a broken mechanical wall with weathered marks. A gigantic tree made from ancient machinery still continues to shine with the memories of those days as a beacon of hope, waiting for the time when it will one day fulfill its true role.
