Hindsight, Part 3: The Battle of the White Stag

From the introduction:

The third part of Hindsight is fairly free-form. Gamemasters should read over the section to get a loose familiarity with the events and goals, but the specific timing will depend on the players' exact battle plans. There are three major, growing problems during the final round; the player characters may split up or work together to solve them, but splitting up may allow them to get through it more quickly.

1. The Imperial troops in Otosan Uchi need a new strategy to win.
2. Seikidera's role in the battle and history must be maintained.
3. The Mantis must not betray the Empire, or all is lost.
