Fullbright Shirren
Source Galactic Ancestries pg. 39
You were raised in one of the shirren colonies, and as a result, you're used to the sun never setting on your work. Having to manually retreat into the shadowed caverns to rest has made you accustomed to working harder on less sleep. You only have to rest for 6 hours to gain the full benefit of an 8-hour rest. In addition, you're resistant to the effects of fatigue; you gain a +1 circumstance bonus to saving throws against effects that would make you drained, enfeebled, or fatigued.
