I kinda had a prompt like this that was being filled (holy crap, back in part2 - asscreedkinkmeme.dreamwidth.org/717.html?thread=3863501#cmt3863501), but it was abandoned by the author (I found them on ff.net and tumblr and asked. Was very sad over this...)

Anywhoo...I second this one! I like this idea better, tbh. (Can I vote Altair as being the one who is kidnapped? >D)
