As for anything with IMP and pacts, and being welcoming, that's not my realm nor am I with them this set. So I'll just speak for myself...

I've actually abstained from threatening LoC because you are the leader and super chill, so you can't say I've been doing it every set since you took over. Then this set happened. It's not old fluff, but it is fluff that repeats old history. Everyone knows when mob starts grabbing clans, it's because he's trying to provoke them, and provoke war. Ask your allies about that one. You should not have to pay because he thinks that LoC can still be a war clan.
