Supplement 3: The Protoss

From the introduction: The Protoss, also known as the Firstborn, are an ancient race that possess natural psionic abilities. Their society is a warrior’s culture, built on perfection, honor, and glory, as well as a religious devotion to their homeworld of Aiur, and the xel’naga that created them. Their technology far surpasses that of other races in the galaxy, and much of it is built to augment and coordinate with their innate psionic ability.
