The Pet Giant Wraith is a towering spectral entity with a semi-transparent, ethereal body that shimmers with a ghostly blue and purple hue. Its form is humanoid but elongated, with exaggerated limbs that taper into wispy ends, giving it a haunting, otherworldly presence. The wraith's face is featureless except for two glowing white eyes that pierce through the darkness, and its body is adorned with faint, glowing runes that pulse with a slow, rhythmic light, suggesting ancient magic. The surface of its form appears smooth yet slightly distorted, as if seen through water, with occasional ripples that emphasize its spectral nature. It moves silently, leaving a faint trail of mist in its wake.
