Precordant

A precordant is a person who was born before the Prometheus Accords - during the 20th and 21st century. Age does not normally factor into social consideration among humans, but this group is a minor exception. Because vast majority of triates are precordants, they as a group are often seen as the pool from which they are drawn from. Many groups focus on eliminating these ancient humans, while others feel obligated to aid in their defense.

As a group, they are also ancestors of a significant fraction of diasporic humanity. Some still find this a bit awkward when engaging in romantic endeavors.
