Carsus
From Tardis Wiki, the free Doctor Who reference
The hot, humid planet of Carsus was home to the pentagonal Library of Carsus. The solar system which Carsus belonged to also included the planets Minerva, Schyllus, Tessus, Lakertya, Molinda, and the lifeless outer gas planets Hollus and Garrett. The surrounding area of space was known for its spatio-temporal anomalies, including temporal waves, reports of strange matter fragments and chronic threads, and rumors of a supernova that exploded in the distant past but mysteriously left no traces.
