Avvy

Spines across her head, with a thick line of fin protruding from her scalp and falling forward like a veil. This can stand up straight against the spines to form a cutting edge, revealing her face when needed. Pure white, milky eyes with a dark diamond shaped pupil. The hair is dark, and curled but turns more wavy at the ends lending to a wild look. A false collar made of bone and frill around the neck, leaving a triangle shaped window to the clavicle. Similarly around the thighs, but with spines along the hip blending with tentacles with webbing between it. These fins and webbing are mostly blue and green with cream colored splotches at the edge.. It curves up around the buttocks, and from the tailbone there’s a finned tail with like tentacles to perfectly control their movements. The curve of the fins on the hips and outer thigh overlap the tail for better control. Along the left and right extremes of the body there is a perfect line, a pale seam as if the skin could be peeled back. In fact, this is used to connect with the rest of her body, a massive fleshy palace that serves as home and shell same. The inner structures seem to be a cross between coral formations and shells, as well as squid’s tentacles with barbed hooks in the suckers and human organs and teeth. The outside is like a dual sided conch, featuring two towers with large gates plated in bone. The spikes along the slow sweep upward are akin to teeth, and are actually joints that allow the flex and pulse in order to attack things larger than she, or to build up pressure to rupture outward in shards of bone and shell. Under the “Doorframe” of the castle like structure flow tentacles and legs like a crab capped at the end with thick bits of bone. Due to the immense size and strange biology of the eldritch, the entire structure of this larger body is built like a castle with carpets of cilia, pillars of polished shell, doorways of gnashing human’s teeth and curtains of membrane. Pseudo-windows framed with glittering, semi-clear bone or shell remain as pods of bio-luminescence, providing a light across the interior.

“Human” body extension and sanity:
The seam on the skin peels back, blooming outward like singular calla lillies into glittering shell and eyes set into gaping sores lined with shards of bone. This unhidden form under the literal skin causes immense pain to parietal lobe, and can prove sanity-blasting if exposure is long enough. Normally it’s too late if one observes this.
