Regarding your question, yes Lord Roahell (whatever his name is.....) attacks your castle. But this event only occurs after you met with him initially (as you have stated) and have completed about 3 more side quests (I think that's the number) before a messager from your castle appears and tells you that your castle is under attack and you need to return ASAP. You get tons of experience when you finish the fighter stronghold.
