Lifeform Reading: Yeti

Yeti are engineered descendants of an ancient survival experiment, adapted to endure the harsh conditions of a frozen world. They have since joined the interstellar community as a recognized sophont species. This supplement introduces Yeti as a playable species for Cepheus Engine and the Original Science Fiction Roleplaying Game. They thrive in arctic environments and large groups, but struggle in warm climates and quickly dismiss those they consider useless. They can interbreed with humans, though their appearance remains distinctly nonhuman.
