tetrapyriarbus
Home planet to the Tetraps, the bat-like creatures that fed off haemoglobin. They were used as slaves by the Rani during her attempts to create a Time Manipulator on Lakertya. The Tetraps eventually turned the tables on their mistress, trapping her inside her own TARDIS and taking it back to Tetrapyriarbus. They explained that her genius would help them in their quest for more blood plasma.
