A player, 18 June 2012
The Snow Has Teeth Winter Reaction: After engaging: The current battlefield's province has a maximum strength equal to its base strength until the end of the battle. Negate the next effect that would move one of your Personalities from its battlefield. After the next time this battle a Terrain enters play, destroy it.
The Power of a Word Political Reaction: After another player's Battle action targets your Courtier: The player may choose to lose 3 Honor. If he did not choose this, negate the action's effects. Battle: Target one to three enemy dishonorable Personalities: The shadow of their shame shall fall upon their shoulders. Move them home.
Regarding the Battle action on The Power of a Word, would The Snow Has Teeth be able to save only one of your Personalities from being moved home or since the wording says "negate the next effect", would it be able save all targets? Or would it not be able to save anyone at all since it specifies "negate the next effect that would move one of your Personalities" and The Power of a Word would move more than one home?

Something that moves more than one of your Personalities also moves one of your Personalities (otherwise it'd say "exactly one"). In this case, since the effects moving the Personalities are happening simultaneously, the active player would choose which happens "first" and is therefore negated by The Snow Has Teeth.
