The Ru were a diminutive, hairy, and undeveloped sentient species of mammals originating from the planet of Phorose. Although the Phorosian inhabitants viewed them as rodents, scientists held the opinion that the Ru were actually sentient, based on their construction and use of temples for worship. These creatures were furry.
Around 20 BBY during the Phorose battle, Padawans Ahsoka Tano and Barriss Offee stumbled upon a Ru community dwelling within a temple located beneath the Phorosian capital. A battle droids patrol, dispatched to neutralize the two Jedi, demolished their temple. While the remaining Ru were being transported away via a LAAT/i, two Vulture droids attacked the gunship, resulting in the death of all Ru passengers except for a pair of survivors.
