"Specimens of SCP-962-1 are cybernetically augmented animals. These augmentations usually force the animals into a bipedal gait, and are often accompanied by crude cosmetic alterations such as the removal of a snout, with the apparent goal of making the servitors appear more human-like. The nervous system of members of SCP-962-1 is slaved to implanted electrodes, which allow them to be controlled by a central source, assumed to be the tower itself.
These servitors fulfill a number of roles. Many of them mine for ore in an extensive system of tunnels excavated below the valley, which is then refined by the tower. Others repair damage to the structure or other servitors. A small number construct roads, apparently to facilitate movement of SCP-962-1. The remaining servitors hunt down and destroy all non-human life in the valley. There are no recorded instances of any member of SCP-962-1 attacking a human or a machine, even in self-defense. Frequently, the corpses of animals killed in these hunts are brought back to SCP-962 for conversion into SCP-962-1. Plants may also be returned for use as fuel. Despite the damage caused by their augmentations, servitors are very effective at their roles, and seem to be built specifically for them." - www.scp-wiki.net/scp-962
