OK, here's the story. If you go for the paladin stronghold quest you will go to the copper coronet and talk to Lord Jierdan Firekraag. He will assign you. Do this quest and after you have saved the child (and in your case killed Firekraag) you go to Sir Ryan Trawl. He'll give you an assignment to investigate a cult of Fallen Paladins

Go to the Bridge District, then on the south east side of your map, there is a group ready to fight (thieves and Fallen paladins). Help the fallen paladins and you'll have to get a cup from the Most Noble Order of the Radiant Heart. Talk to Ryan Trawl and get the cup. Then you will meet Anarg. Anarg will see through your scheme but his right hand (don't know his name at the moment) will not fight you. Kill the rest of the fallen paladins and Anarg and return with the cup to Ryan Trawl, you'll get the golves of healing.

After that you'll have to go to Sir Reirrac (if he's not there talk to the Prelate).......from this point I'll leave you one your own. If you still can't finish it, ask me again.
Hope it works.
