Myarr

Myarr is one of the galaxies last fertile planets. Pilot Kelivin told The Doctor that if it fell there would be a famine across the galay. It is home to humans, but the Mantasphids had invaded the planet just for dung, so a war sparked out. The Doctor and Martha Jones ended the war, by pretending to be controlling the Mantasphids by keeping their queen hostage. The humans and Mantasphids decided to live in harmony on Myarr.
