I'm looking for a 5e 4- hour one shot suitable for a four person party of multiclass sorcerers sorc 3/other 3.

As part of that i would be allowing either Intelligence or Charisma as the casting stat.

Two scenario ideas i had in mind (although not committed to) are in a Harry Potter wizarding world-esk environment or a special forces unit (seal team) scenario.

Anything out there already that may work for this, really dont want to go to another rpg system.
