Dronid

Dronid was a Gallifreyan colony. Its name should have been Drornid but there was a typo in a first edition of Bartholomew's Planetary Gazeteer so the rest of the universe (except the natives of Dronid) called it Dronid.

History
A Gallifreyan Cardinal once attempted to set up his own High Council on the planet Dronid. He put together an army with the hopes of overthrowing the Gallifreyan High Council. He was dragged back to Gallifrey, leaving a lot Gallifreyan time technology still on the planet. (EDA: Alien Bodies)

Dronid was well known for its warp-poets. (EDA: The Tomorrow Windows) The first battle of the Second War in Heaven took place on Dronid. (EDA: Alien Bodies)

Behind the scenes

 * On Dronid's name Lance Parkin notes that "[i]n the note about Drornid it's claimed that I got the name of the planet wrong in A History of the Universe. The spelling 'Drornid' appears in the script which came with the video (of Shada). The spelling 'Dronid' first appeared in The Universal Databank— the joke that Lawrence is making is that so many people read the 'guidebook' without checking the facts that the name 'Dronid' stuck in the end! For the record, it's spelt 'Drornid' in A History of the Universe (p.251)."
