Operation Starwatch was a government agency set up in the United Kingdom on Earth for the purposes of protecting the planet from alien invasions. It was under the control of Colonel Granite, who eventually subverted it and diverted military funding for his own ends, intending to use Operation Starwatch to conquer both Earth and planet Mobius, which they would then sell off to industrial developers for profit. Starwatch has two bases, one in London and another somewhere in Scotland.
