It has nothing to do with the dragon. You have probably completed the scene in Val Royeaux with the Chantry and the Templars. After this you need to talk to your advisors back at Haven. If you've tried this, did you see the cutscene in Val Royeaux where Fiona introduces herself? It may not trigger if you try to fast travel out of the area instead of using the exit. Try exiting manually. If, when you approach Redcliffe gates after this, a rift does not appear, then I'm afraid you've hit a bug, but at least you can progress the main story by siding with the Templars.
In the Mage Tower, a Desire Demon has entranced a Templar. Should you choose to fight her, you will have to kill the Templar also, and he has the Templar Armor.

No. Dragon ball and dragon ball z follow the storyline of the Dragon Ball manga, which ended quite a while ago. With the manga storyline finished, the television show has finished too. Dragon Ball GT was made however, to see if Dragon Ball could continue a storyline without following the original manga, but that was in total deemed a failure by almost everyone, including the creator of Dragon Ball, who refuses to acknowledge it what so ever, claiming to have nothing to do with it, and disagreeing with it even before it was made.
You in fact must get married in Dragon Quest V, it's a critical part of the storyline.
