Cal is currently studying some old tomes he found in the Royal Library on Theed about the basic lightsaber styles; he wants to train in them before heading to finally make one of his own. Rane could stumble upon him and it could go from there?
Actually, I just started thinking. Maybe this could be canon; especially if it is on Naboo. Could be that these two become good friends or even rivals, depending on how the fight goes. You okay if it's a canon, no-death duel?
