Effenish
From Tardis Wiki, the free Doctor Who reference
Effenish was asked for the surrender of Trematz but no-one responded. She then upped her warning and bombarded the plane and later then invaded the planet. She got annoyed when her squad when distracted by the singing rivers. She thought that the only way get the people of Trmatx to listen was to plant bomb on their planet. (AUDIO: The Very Dark Thing)
