Opiders

Opiders are spider-like creatures with smooth "pebble"-like bodies and six special tentacle-like legs. They have no vocal cords, therefore they cannot talk. Nor do they have ears, which means they cannot hear.

However, Opiders posses six eyes that are quick to scan their environment and make up for their loss of hearing.

Communication
Opider communication is solely visual. Their bodies change colors within several spectra of light to communicate. They also posses an appendage on the top of their bodies which projects patterns and lights as well.

To communicate with Opiders, one must enter the Degree II Special Vision which allows "translation". However, this translation is never completely accurate. Opiders are also required to enter a similar abstract translation state.

Bodies
Opiders have small pebble bodies which are very smooth to touch. Opiders non-communicative body color is either white or black, sometimes featuring golden patterns to signify age or rank.

The pebble bodies resemble a "squished" sphere.

The tentacles aren't actually tentacles, they are appendages with hundreds of joints and bones. This allows the appendages, along with strong muscles, to behave as if without bones. Opiders are able to "lock in" the bones and make their appendages stiff. They use this to become formidable opponents.
