if a personality is destroyed while dishonored, and you lose the honor from it, is it counted as losing honor due to one of your cards? Or does 'No Mercy' only count for cards like 'hired killer" in which the card states "lose x honor"
No Mercy and dieing dishonorably
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.

You left the operative word out of your question, and that word is "from".*
No Mercy reads, "Until the end of the game, any player who has suffered an Honor loss from one of his or her own cards is eliminated if his or her Family Honor is below -14."
The Honor loss due to your Personality dying dishonorable is from the rulebook, not your card. No Mercy will not affect you for only that.
*EDIT: Okay, you didn't leave it out entirely; it's just in there as a "given" rather than part of the question. Really, I'm sorry if my reply was rude-sounding; I'm quite tired and should go to sleep now.
