The term "Shoulder Chimera" refers to the entire class of creatures artificially made by Synth a sign of status. As the term implies they are often carried around in the shoulder, but the key component is being somewhat portable. They are the result of extreme and extensive Synth alteration with the goal of merging traits across species, creating unique hybrids. Such beings are nearly universally infertile, in pain, have health problems and have short lifespans. Creating one is such an unsure process that for every Shoulder Chimera that lives to be old enough to be used twenty or more will have died.
