Hm. That's good city suggestion although it could take a while to imminent all the tyoes that would go there, but I will work on it.
And that first one will be answered eventually, the plot will kick in at some point to explain it. As for weapons, sure you can use any normal means at your disposal, and equip cards and spells (for example: banner of courage) other than that, I don't see a person doing much to a monster that's really strong (such as red eyes black dragon)
