Torcrist

Meet the torcrist. It is basically biological power armor for the much smaller invertebrates known as torcrid. Technically alive, it has no higher brain functions, and requires the symbiotic bonding with the torcrid to survive. While technically eyeless, most of its epidermis is photoreceptive, and the torcrid symbiote is able to process the massive amount of visual data this yields, essentually granting omnidirectional vision. Another fascinating aspect of supporting a torcrid host is its ability to rapidly alter its host's body structure to suit its needs. The detail and aesthetics of such transformations will vary from torcrid to torcrid, depending on their own artistic talents and preferences.
