Okay, i went and talked the the fallen paladins then got the guys cup from the order of the most radiant heart. when I got back and gave it to the leader of the fallen paladins he attacked me so I killed him and his team and then went back to the order with the cup and news of their deaths. The leader of the order was greatful and gave me gloves of healing but wont give me any more quests to become a knight of the order, why?
I don't know if this is correct. I thought you have to kill that red dragon guy, get holy avenger, then some messager will come to tell you the most radiant heart needs to see you.
The final quest for the Paladin stronghold is to kill Fierkraag, and thereby you obtain the sword that is so good for them. But you can kill the dragon before ever going there, and still get the Stronghold.
