Jagged, obsidian-like shards of the crystal protrude outwards, catching the faint, ethereal glow emanating from within. The immense structure, crafted from weathered, dark grey stone, rises majestically against a bruised purple twilight sky. Intricate carvings, depicting swirling arcane symbols, adorn the weathered stonework, their lines etched deeply. A faint, almost inaudible hum resonates from the crystal, vibrating through the stone tower. The air around it crackles with an unseen, magical energy palpable, like a silent vibration.
