Well, sometimes they beleaguered each other, than again they were friends and played jousting :-)
From the set history I have to vote "Lion Knights". And since those two (LK and BF) are the "classic" factions of the Golden Era I usually let them fight each other. And I really don't think the Forestmen hate the Falcons. In fact I think Robin of Locksley is a former BF himself, forced by the evil myrmidons* of the Black Monarch to leave his manor and hide in the woods...
*) Yeah, I had to look up this word. I'm quite sure I will not remember it for further use :-)
And Will, you are right, those smilie faces really can get annoying...
Otherwise Black Falcons are not looking up to anyone.
This is just the sort of nonsense up with which I will not put.
