Lithodia Rexian

Lithodia Rexians are a stone-like sapient species from Lithodia Rex, who placed dormant agents on Easter Island.

Biology
Lithodia Rexians are large, silicon-based humanoids, with heads that bear a strong resemblance to Moai, with an oblong shape, flat tops, heavy brows, large noses, featureless oblong ears, and somewhat protruding lips. Additional features include four fingers per hand and visble crack-like segments on their bodies. While their lifespan is unknown, they are able to lie dormant for centuries. However, they have referred to Humans as "mortals," implying that Lithodia Rexians are immortal. They possess incredible strength and durability due to their silicon-based bodies. While Lithodia Rexians are quite powerful and intimidating, Humans can easily outmanuever and outrun them. Lithodia Rexians also appear unable to swim, instead walking along the sea floor.

Culture and society
Lithodia Rexians are imperialists, sending out dormant agents to planets of interest to wait for the right time to invade. These agents are often planted in the ground, seeming to be statues, and can wait for centuries, although they are known to wake up at certain points in time to check for orders from Lithodia Rex. Native species of conquered worlds are forced to become slaves, while their planets are turned into Lithodia Rexian colonies. Any natives who witnesses them moving prior to an invasion or otherwise learns of their alien nature or schemes are to be captured and executed before they can warn planetary authorities. However, if the witness is unable to get authorities or the populace to believe them, the Lithodia Rexian agents are known to deem the witness no longer a threat and return to their dormant state. Lithodia Rexians, or at least their sleeper agents, are known to wear no form of clothing, likely because they have no visible genitals and because their bodies are already very strong, and so that they could easily pass for a statue.

Technology
Lithodia Rexians are advanced enough to travel faster than light, easily bridging the gaps between their world and other planets. Dormant agents also have some form of interstellar communication devices to stay in contact with Lithodia Rex over hundreds of years.
