A vast organic creature with a body resembling a massive interdimensional jellyfish. With a large, amorphous central trunk, its tentacles extend in all directions, each covered in a thick layer of bioluminescent cells that emit a pulsating glow. In the center of your body, a giant multifaceted eye serves as the core of its perception, constantly rotating and observing everything around it with frightening precision. Its skin is a combination of gelatinous and prickly textures, able to adjust and change as needed.
