Relentless. Unequalled. Sadistic.
Though originally equal in physical stature to the other elder brothers, the descendants of Therrin have warped both their basic bone and muscle structure (shifting their posture and load-bearing stances). In addition, social mutilation, as well as specific functional use of both tooth and nail over millennia, have promoted the rapid development of organic weapons now born to all Therrin. Intense climbing, running, sprinting from trees and close combat engagement have forced the development of dense bone and muscle tissue.
Genetics and Reproduction
Unlike all other races upon Elämä, Therrin are only a fraction of other populations. This is almost entirely due to the lack of female options and the overwhelming desire to kill, rather than reproduce.
Perception and Sensory Capabilities
A Therrins sense of smell and hearing can be compared to that of a wolf, while thousands of year working in both shadow and the dead of night have allowed them to hone their tracking skills to near-mystical levels.
