- War ended early 20th century with the rise of Praetor Sartorix (ENT Novel: Uncertain Logic)

- To be done by directing society towards a more aggressive footing, disconnecting them from Surakian values through manipulation of the historical record, framing natural telepathic talents as shameful, etc. (ENT Novel: Uncertain Logic)
- In truth, the goal was to weaken the High Command through military action and Vulcan society as a whole to make them easier opposition to conquer, as was part of the Earth-Romulan War in 2156 (ENT Novel: Uncertain Logic)
- Claimed to embedded sleeper agents that the goal was to redirect efforts from fighting Vulcans to shaping them, reforming their society through infiltration to a position where they would be appropriate for returning to the Sundered, reunifying them into a single people (ENT Novel: Uncertain Logic)
