Variant: Non-Hierarchy:

During the Unification War, Turians began utilizing facial markings to differentiate themselves from members of other colonies, a tradition that exists to this day. However, some Turians choose not to receive these markings; others may have grown up outside of the Hierarchy. Whatever the reason, a barefaced Turian is generally associated with someone who is beguiling or cannot be trusted in Turian society. However, as with any society, an individual’s perception of the “bareface” stereotype might be anywhere from extremely potent to completely indifferent.
