History
The Mantasphids had invaded Myarr and attacked the human population there. There was an all-out war on the planet, with the Mantasphids building huge hives in the forests. The Mantasphid Queen had revealed that they need the pkanet for its dung from the animals. She had hired Meregrass, a frog-humanoid, to be their military advisor. When the Doctor and Martha arrived, they had stopped the war and now humans and the Mantasphids live in peace on Myarr. (The Infinite Quest).
