A player, 26 October 2008
Limited: After each battle resolution in which you destroyed one or more Provinces or units as the winner, you may target a Personality; if you do, dishonor him, and his controller loses 2 Honor.
Assume I played a Peaceful Interlude, and later in the Attack Phase I destroy a province. I trigger the conditional indefinite effect and try to target a personality of the other player.
Can he react with Misdirection / Seat of Power to choose or change the target of the effect? Or is it too late for changing targets for the Peaceful Interlude?

Seat of Power, yes (assuming a Champion or Daimyo is involved). Peaceful Interlude is an action, and it's targeting, which is the trigger for Seat of Power.
Misdirection, no. http://rules.l5r.com/Rulings_M#Misdirection: "The timing point of Misdirection's action trigger is: during the other player's action's Required Targeting Step, in between the last required targeting in the constraints block (if any) and the first required targeting in the effects block (if any)." It cannot respond to delayed targeting.
(Fixed.)
