The Pet Wraith is a spectral companion with a translucent, ethereal body that shimmers with a faint blue or purple glow, suggesting its otherworldly nature. Its form is humanoid but slightly elongated, with wispy, trailing edges that dissolve into the air, giving it a ghostly appearance. The wraith's face is featureless except for two glowing eyes that pierce through the darkness, and its body is adorned with tattered, floating remnants of what might have been clothing or armor, adding to its haunted aesthetic. The surface of the wraith is smooth yet subtly textured with a mist-like quality, and it moves with a floating, weightless grace.
