Tarquin has a back up weapon. I know this with great certanty because the man carries a dagger some where easy to get to in his own stadium, with hundreds of guards running around and a red dragon too, all willing and ready to help him if need be. Now he's on an adventure, knowing he's headed into a dungeon or some other place that will involve lots of combat with only 5 people to support him. He has that dagger stashed some where on his body, or prehapse something better than a dagger. Is it really that hard to believe?
