Temporal Scanning Service

The Temporal Scanning Service was a governmental agency on Gallifrey which monitored the web of time for signs of temporal interference. Their work was overseen by a special sub-committee of the High Council. They once detected a severe incursion caused by Players which demanded a creative response. The TSS' oversight committee recommended dealing with the problem by sending a special aget. Since the Second Doctor had just been condemned to death, the sub-committee reasoned, he was an excellent candidate for working with the Celestial Intervention Agency to solve the problem that the TSS had detected.
