Procyon Two
From Tardis Wiki, the free Doctor Who reference
Procyon Two was the homeworld of the Kobolds. When the TARDIS materialised on Procyon Two, it started to alter the Kobold language, but the job was only partially finished when the Time Lords brought the Third Doctor back to his exile on Earth. As a result, the Kobolds could only use the vowels "o" and "y". War ensued after this event. (PROSE: Morphology)
