Thia

Known as the "Large, fast moon", Thia is the primary natural satellite of Ethru. Its apparent diameter is larger than that of its sister satellite, Edu despite being further away. Although it orbits at a slower speed than Edu, the rotation of Ethru makes it appear to move across the sky faster, much like the Moon does when seen from Earth.
