Elin Roe, a celestial object found within the Elin Roe system, was a Colonies world. During the era of the Galactic Civil War, Hallyn Phlynne was responsible for patrolling this system. This world possessed a minimum of five moons. As a result of the Krish mechanic known as Maniac tampering with the hyperdrive of the Yagaran Four's freighter, the fifth of these moons was subjected to a bombardment of radioactive dust; the starship exploded in its attempt to jump to hyperspace.
