Our heroes (at least the majority of them) meet for the first time at the Heroes Guild Team Formation Center. It is mostly dominated by the mind-reading teenager being a hero for Community Service.
After a brief car-juggling event in the parking lot, our heroes are informed that the nearby Museum of Generic Science and Human Culture is under attack by a strange group of people, so we head out to look into it.
Arriving on the scene, the cops are keeping civilians out of the museum. After a brief bit of information gathering, we head in to do our civic duty, and are immediately set upon by some men in ridiculous looking yellow and black hoodies.
