Climbers are one of the most prolific of the subspecies of Nalorgians.  Climbers were a common sight in the Empire of 1,000,000 Suns, and the Nomad Armies throughout Era-0.  During Era-1, Climbers spread throughout the galaxy due to contact between the Nomad Armies and the Planetary League.

While most subspecies of Nalorgians came about after Cielioids from the E1MS brought advanced biotechnology to Artanis 4, Climbers actually pre-date first contact between the Nalorgians and the Empire. 

Anatomy and Adaptations

Climbers likely originally evolved to survive in the mountainous parts of Artanis 4, and their bodies are the strongest evidence of this. 

Climbers have three legs and three arms each (typically in ratios of two female to one male, but all configurations can be found in the population), which gives them better footing and an extra hand for grabbing handholds.  The arm and leg symbiontes are virtually identical to those of most Nalorgians, with whom they can easily trade limbs. 

The body of a Climber is spherical with a hard, bony shell.  Like a turtle, Climbers can retract their limbs and heads inside their shells. 

The head symbiont has a cap of the same shell material that covers the body, this protects the head when the Climber retracts it.  The eyes on the front of the Climber's head are widely spaced, and they have a third eye in the back of their heads, granting the Climber 360-degree vision.
