Torre de mago

// «Torre de mago» · gpt-6-sol (medium)
// A tall slim wizard's tower of round mossy grey stone, slightly crooked and wider at the base, with small arched windows glowing warm yellow, a wooden arched door with steps, a balcony ring near the top, and a tall pointy cone roof of deep purple-blue tiles with a little curl and a golden star at the tip. A small glowing crystal-like window at the top room.
