This is of a planetary scavenger, one who scourges desolate planets in search of sustenance.... They are ruthless and unyielding, because of this- they are most often found in small groups. These groups usually consist of pitiful beings that bend to the Scavenger's will, asking little in return for it's protection. Being machines, they usually outlive their group- This comes as little pain for the Scavenger as it can find more to replace the fallen member, and that it never cared anyway.
