Bianca ' s Cabaret Bianca ' s Cabaret was an exclusive nightclub situated on a planet in deep space , at a nexus of dimensional wormhole s . It was used as a staging ground for the takeover of the universe by psychic worm s of different factions . Description . Bianca ' s appeared to be a simple cabaret nightclub from 1930s Berlin . The insides were fairly close , with many individual and private booths , and a main stage where vocalists could perform . While capable of supporting a full band , performances were generally limited to a single piano player . Bianca , the Chanteuse of the establishment , would sing various songs in short performances over the course of the night , with her final performance at midnight . Mickey , Bianca ' s head waitress , described the club and its clients : In reality , the nightclub was the remains of a TARDIS stranded on a planet in deep space , at the centre of a dimensional nexus . Henry , the manager , would arrange " special taxis " that would pick up and drop off patrons through wormhole s from various points in time and space , including the planets Astridia , Darganon and Earth . Henry spent much of his off - time making sure the club was dimensionally stable against the chaos of the nexus . The description of the the outside suggested the club was small enough to walk around , and that there was a breathable atmosphere on the planetoid . Outside offered an excellent view of the stars , when it wasn ' t covered up by the maelstrom of the dimensional void ( seen as a heavy mist ) . ( AUDIO : " The Wormery " ) History . Bianca , a wayward Time Lady , had landed on this small planetoid as her TARDIS was breaking down , and heard the call of the psychic worm living there . At their behest , Bianca worked with Henry to stabilise the local area , build a nightclub inside the stranded TARDIS , and assemble a trans - dimensional " taxi service " that would deliver patrons to the club through the wormholes . Bianca would provide the main entertainment , with her singing enhanced by the worms ' natural psychic abilities . The Sixth Doctor showed up at Bianca ' s one night , weary from his travels and looking for entertainment and diversion . He found Iris Wildthyme there , babbling about voices she could hear only when she was thoroughly drunk . Investigations quickly found that the worms were using the nightclub for various purposes : a " pro faction " was using Bianca to project a universal moment of harmony , an " anti faction " was using Iris to project a universal moment of chaos , and a " shadow faction " was using Henry and the other factions in a plot to take psychic possession of the club ' s patrons and the rest of the universe ' s inhabitants . The shadow faction managed to gain the upper hand , and were able to take over most of the club ' s patrons . In an effort to stop the shadows ' spread across the universe , the Doctor used his own TARDIS as a time ram against the club , virtually destroying it . ( AUDIO : " The Wormery " ) Notes . The " house special " was very similar to tequila . It was made on the planet Sagis Minor , and was used by the worms as a means to bring humans into simpatico with them . ( AUDIO : " The Wormery " ) Among the patrons who frequented the club was an observer from the Celestial Intervention Agency . ( AUDIO : " A Blind Eye " )
