need help

I assume you have met Dorian, and then don't know what else to do....which is to go back to Haven, and into the chantry church back room to the Main Map.  On the right side of the map should be two icons with glowing green balls of flame(best description I can give for it I think), which indicate main mission items.  One mission should be to go after the mages, and the other mission should be to go after the Templars.  If you don't have enough points to do either, then you will have to do items such as quests or closing rifts to gain the necessary points.  The choice between mages or templars is an either or, so whichever you pick will effect things in the later game along with giving a different quest for this choice.
