The lithe humanoid is without any distinct facial features other than the vague impression of a nose and indents where eyes should be; though there is a golden glow implies ocular organs of some sort under its epidermis. At first glance, one might think this is due to a pale cloth drawn tight over its visage, but whenever the creature moves its plain that is some sort of artificial skin. The rest of its body is a smooth crimson shell of molded musculature. Raised, thicker and darker patches of skin form intricate patterns across its shoulders, down its spine and each arm.

The synth grinder wears a cross-halter top with spaulders attached that have a barbaric design. Its gloves, however, are bulky and unlike anything known on this sphere. The right hand doesn't end in fingers, but in a trio of buzzsaws equilaterally arranged around hole filled with grinding gears. The left hand has thick fingers, but a swirling flame under glass dominates the back of the forearm. From the gap in that hand's palm that the synth can produce a white-hot beam.

Societal Ennui. Synth grinders are the most numerous of synths. They serve as guards for the rest of their race and serve the synth chaser without question. Synth grinders reduce the skulls and spines of other humanoids down into necrotic mnemonic. When ingested, this powder instills the consumer with the memories and skills of the slain creature. Birthed in vats while their vessel travelled between the spheres, the synths have no identity of their own and ruthlessly harvest those of other humanoids. They see other thinking beings as a resource to fuel their addiction for the recollections supplied by the necrotic mnemonic are fleeting. Once gone, only a hollowness remains the synths will do anything to fill.
