Morphology: Humanoid. Their median height is approximately 15 to 20 feet tall. They are thick and brawny. Their skin is covered by armor plates. Their heads are adorned by fierce-looking horns. They have no hair except for patches of bristles between their armored plates.
Notes: Indigenous to a world that no longer exists, Trolls are vagrants who live in massive spacecraft. Their primary industry is planetary rehabilitation. Their city-sized tool is called Planet Builder. This tool works to transform the biosphere of a planet as a whole. Some focus on atmospherics and position themselves at convection points for maximum circulation of their processing. Others focus on the terrestrial biozone, turning rock and lava into soil and planting in a succession of plants to make this soil live. Still others affect the oceans, lakes, and rivers, cleaning and building ecosystems in the waters. The Trolls are brilliant, passive for the most part, but a little grumpy at interruptions.
