fantasy art, create an image using the following description: a stone building of formidable stature. Its walls, crafted from prestine mithril stone and adorned with intricate carvings, exude an air of mystery and intrigue. At its center, a large plasma globe pulsates with energy, casting an otherworldly glow that illuminates the surrounding area. At the top of the building, a weather vane stretches towards the sky, its metal tip crackling with electricity as lightning arcs upwards, drawn to its magnetic pull. The air hums with the sound of energy, a constant reminder of the research and development that takes place within the walls of the stone building.
