Design an epic fantasy SKYBLOCK map called Obsidian Shores. The hub should feel like a handcrafted server spawn built by a professional Minecraft builder. Theme: Dark obsidian cliffs meeting brilliant turquoise ocean water Volcanic island with ancient ruins Massive obsidian formations emerging from the sea Lush tropical vegetation growing among black stone Mystical purple crystals and glowing amethyst caverns Floating islands connected by elegant bridges Ancient civilization aesthetic mixed with fantasy magic
