[member="Darren Onyx"] Great question!
We'd like to keep this to 20 people in-game only, because if people are allowed to bring other characters it will start to dilute the danger of the game itself, if that makes sense? More people vs. the Bad Guys lowers the stakes.
HOWEVER, if you want to have your NPC watching the show, or trying to figure out where it's held to help Darren escape, that's more than fine. Details will be incoming on the day we get started, but the show is held on a very deep level of the New City on Maena, and is extremely secretive and well-guarded. But Six & I have no problem with the NPC getting involved in a way that's outside the 'venue', per se.
Any questions/clarification, feel free to ask!
