Racial trait

Racial traits are essentially racial picks updated for Master of Orion.

Some of the traits listed here are "hidden" in the game and not normally available on the custom race screen. They are either exclusive to a preset race, meant to be obtained through one of the special abilities bundles, or used behind the scene by one of the non-playable factions (Antarans, pirates, and space monsters). Hidden traits are listed in a fainter style.
