Kasatha Heritages
A kasatha's heritage might be influenced by the environs their ancestors inhabited on Kasath, the lineage they were born into, or their progenitors' role in their peoples' interstellar migration.
Akitonian Kasatha
Source Player Core pg. 55
You (or one of your ancestors) traveled to the Pact Worlds on the Idari and settled on Akiton. Akiton's significantly lower gravity grants you an advantage in the fun and practical art of leaping, and you likely revel in the many rituals surrounding the desert world's popular sports. You gain the Quick Jump feat and don't treat sand as uneven ground.
Kasath Survivalist
Source Player Core pg. 55
You and your ancestors were among those who chose not to abandon your dying home world. Your people trek through wasted lands under dim skies, seeking shelter and resources even as they slowly dwindle. You might have finally decided to seek a better life, or perhaps you hope to convince others to return to Kasath with you. You can Hustle twice as long while exploring before you have to stop. If you're in a group that's Hustling, you increase the total number of minutes the group can Hustle by 10 minutes, or by 20 minutes if you're 13th level or higher. You gain the Feather Step feat.
Shipborn Kasatha
Source Player Core pg. 55
You were one of the kasathas born and raised on the Idari worldship that now orbits the Pact Worlds' sun. Your family kept hope and tradition alive while enduring the hardships of lengthy space travel. For you, the Idari is the only home you've ever known. When you roll a success on a saving throw against an emotion effect, you get a critical success instead.
Stellar Nomad Kasatha
Source Player Core pg. 56
You choose to travel abroad, leaving your birthplace to embark on a journey through the wider cosmos. During your daily preparations, you can study a particular ancestry, faction, philosophy, or religion to learn one of their edicts or anathemas and gain a broader understanding of that culture's customs and traditions. While you follow that edict or anathema, you become trained in the associated lore (such as Vesk Lore or Damoritosh Lore). This proficiency lasts until you prepare again. Since this training is temporary, you can't use it as a prerequisite for a permanent character option like a feat or a skill increase.
Tempering
Source Player Core pg. 56
You're undergoing your Tempering, a coming-of-age ritual during which a kasatha rejects the formal traditions of their family and experiences other customs and traditions. You might be one of the Untempered, a kasatha who chooses to continue their Tempering beyond the traditional period. You become trained in Society and gain the Streetwise feat.
Versatile Heritages
Borai
Source Player Core pg. 85
You've returned from the brink of death as a borai— at once both living and undead. You gain the borai and undead trait, in addition to the traits from your ancestry. Unlike other undead, you don't gain void healing. You're healed by vitality effects and damaged by void damage, as if you were a living creature. Likewise, you can be stabilized, healed, and brought back to life as if you were a living creature, save that you always return to life in your normal undead state (as a borai). You gain low-light vision, or you gain darkvision if your ancestry already has low-light vision. You can choose from borai feats and feats from your ancestry whenever you gain an ancestry feat.
Prismeni
Source Player Core pg. 89
You have an innate connection to the Drift. You gain the prismeni trait, in addition to the traits from your ancestry. While you're in the Drift, you can automatically pinpoint the location of Drift beacons, Drift lanes, Drift engines, and other Drift-related technology within a 100-mile radius. If you're Piloting a starship that doesn't have a Drift engine, you can serve as a connection between the Drift and that starship. This is a 1-minute activity that has the concentrate trait, and it allows the starship you're Piloting to enter or exit the Drift. Once within the Drift, the starship travels via conventional thrusters, as normal. When you get a critical failure on a Piloting check to Navigate or Plot Course through the Drift, you get a failure instead. You gain low-light vision, or you gain darkvision if your ancestry already has low-light vision. You can choose from prismeni feats and feats from your ancestry whenever you gain an ancestry feat.
