Specifically look at the box to the right, what it promotes from and into varies each game. So this is bound to cause a lot of confusion, we should probably pick a game (9 or 10 due to Laguz I'd suggest) as a base to get our classes off of.If you want a class not from fire emblem we could find a way to work it into another promotion tree.Thoughts?

sacred stones is a fire emblem game lol. the knight class usually can choose between a great night (a armored mounted unit with axe/sword/lance) or a general (a beefier knight with the ability to use all physical weapons including bows)
"In Fire Emblem: The Sacred Stones, Knights are one of the promotion options of Recruits, and may promote into either [url=http://fireemblem.wikia.com/wiki/General]Generals[/url] or [url=http://example.com]Great Knights[/url]"
