A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.
Kitsune Den Political Limited: Destroy this card: Rehonor one or more target Dishonorable Personalities. Gain Honor equal to the highest base Personal Honor among them.
Flight of Doves Air Limited: Bow this Shugenja and destroy this Spell: Until the end of the game, abilities on a target Holding produce 1 more Honor whenever they produce Honor.
If the Den targeted by Flight of Doves and is destroyed, if it is brought back into play, will it still be receiving the effects of Flight of Doves?
Ongoing effects that affect a card in play persist when the card leaves play, unless something else intervenes (for example, the Tracking rule - see above).
and Tracking rule:
“Memory” of the status of individual cards ends when the card enters a deck or a hand, or otherwise becomes both face-down and out of play
