Allis and Ballis
From Tardis Wiki, the free Doctor Who reference
André Allis and Vertigo Ballis were dimensional physicists from the planet Astridia. Ballis wrote the book Interstitial Anomalies in Eleven-dimensional Structures. Allis rewrote the book soon after. The two were extremely fond of each other.
One of their multi-dimensional collaborations collapsed an entire star system. They stayed on the Most Wanted list for years afterward. As a refuge, they frequented Bianca's Cabaret, where they were put to subtle use trying to stabilise the multi-dimensional maelstrom outside the club. (AUDIO: The Wormery)
