Grover could be another main character. His reactions to the crazy dares and truths would add a lot of humor and charm to the fanfiction. He might be the one to try and keep the game somewhat civilized, but fails miserably.
In a Truth or Dare round, a girl chose truth. We asked her who she thought was the nicest person in the room. She gave a really heartfelt answer about how she thought everyone had their own kind side. It led to a really nice discussion among all of us about the good qualities we see in each other. It was a great way to turn a simple game question into a meaningful conversation.
One interesting plotline could be Percy getting really wild and unexpected dares that lead him into all sorts of comical or heroic situations. For example, he might be dared to swim to the bottom of a magically enchanted pool to retrieve a lost artifact.
Well, in some 'Harry Potter plays truth or dare fanfiction', there might be a scenario where Harry is dared to ask Snape a very personal question as a truth.

In a Truth or Dare session, I chose truth. They asked me what my most embarrassing childhood memory was. I told them about the time I fell asleep in class and snored really loudly.

Obviously, Harry, Hermione and Ron are the most likely. They are the main characters and are always together, so it's natural for them to be playing truth or dare.

Well, I think Tyson, Percy's cyclops half - brother, would be a great addition. His simple - minded but strong nature could lead to some really funny dares and unexpected truth answers. Also, Clarisse could be included. She's tough and no - nonsense, so her participation would surely spice things up. When it comes to the game, she might give really challenging dares or be brutally honest with her truth answers. And of course, Chiron, as the wise centaur, could also join in. His age - old wisdom would make his truths very interesting and his dares would be both challenging and educational in a way.
