Titan's Heart is a high-fantasy, anime-inspired artifact resembling a pulsating, crystalline core encased in jagged, volcanic rock. The core emits a faint, amber glow, with veins of molten energy coursing through its surface, suggesting immense primal power. The surrounding rock features intricate, natural fissures and is textured to appear rough and battle-worn, with a mix of matte and slightly glossy finishes to mimic cooled lava.
