A tragic incident shakes human-Vulcan relations to the core when a bomb is set off in a protected area of the United Earth Embassy that claims 43 lives, including that of Admiral Forrest. The bomb detonated just before the High Command may have been announcing its intent to conduct joint missions with Starfleet. In the throes of the blast, Forrest actually saved the life of an extremely grateful Soval. As Enterprise is called to Vulcan after the tragedy, Soval comes aboard the ship with the head of the Vulcan High Command, Administrator V'Las, and his security chief, Stel. With the embassy officially on Earth soil, Captain Jonathan Archer is to handle the official investigation. The initial research from the bomb fragments that Mayweather and Reed extricate finds the DNA fingerprint of a Vulcan, T'Pau. She is a member of the Syrrannites, a zealous Vulcan sect that believes in - among other Vulcan taboos - the practice of mind-melding. Syrrannites follow a corrupted form of the teachings of Surak, the father of Vulcan logic who is considered the most important Vulcan who ever lived. A wanted man named Syrran is the sect's current leader. With a Syrrannite now suspected, V'Las announces that Vulcans will take over the investigation.
