Brolfi, or a single Brolf, represented a species of furry, sentient beings. These beings resided on the planet named Barlok. The texture of their skin, known as hornskin, presented in a range of green and yellow colors, and it would visibly tremble when a Brolf experienced strong emotions. They were also characterized by their short, thick legs.
Prior to the Clone Wars, during the period when the Galactic Republic was in the planning stages for Outbound Flight, Caulfmar held the position of governor on Barlok.
