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.
Wary peace:
Target another player who controls an attachment and destroy your target attachment. He may choose and destroy one of his attachments. If he did not choose this, gain Honor equal to the Focus Value of your destroyed attachment.
Suppose someone uses Unsettling Gathering on my attachment and transfers it to one of his personalities. May I play Wary Peace and target it while it is under his control?

No. In this instance "your" references control, not ownership.
