Pathfinder RPG (1st Edition) Starfinder RPG Pathfinder RPG (2nd Edition)


The Starfinder Roleplaying Game is about more than just meeting aliens—it’s also about playing alien characters. In Starfinder, the word “race” usually refers to an intelligent, selfaware species whose members can be considered characters rather than simple monsters. While not all races are appropriate for player characters, many of them are; any creature with a racial traits entry is a member of a potentially playable race, provided that your GM approves it.

Tromlin Hardshell

Source The Liberation of Locus-1 pg. 63
One of three sapient species native to the Gjor III in the Azlanti vassal system of Gjor, tromlins are a bellicose people divided into two distinct subspecies who warred for ages on the plains and forest floors of Gjor III. The bloodseeker strain is a bipedal, reptilian humanoid, while tromlin hardshells are natural quadrupeds. This ancient war is egged on by belief in tribes of warring spirits. Bloodseekers kill and eat any being too weak to oppose them, while herbivorous hardshells fight against their flesh-eating kin.

Tromlins stubbornly resisted the Star Empire, but the two subspecies were unable to unite, and their technology was not advanced. Each surrendered to enslavement to forestall extinction. The Azlanti turned the warrior ethos of tromlins into a recruiting tool, and both subspecies became regular draftees into the Azlanti Alien Cohort.

Even when serving in the same army, tromlins require strict leadership to prevent their rivalries from breaking out into violence. Mixed tromlin squads have yet to be deployed in offensive operations, but the imperial military has found success with tromlins of each subspecies working alongside each other in garrison duty.
