What happened before the Vampire Invasion(based off of rp)

[horselover1009]

" What are you crazy Jake! We're not leaving you here to get killed do ya hear me!" Tsume yelled. Grabbing the nearest thing he could find Tsume went over and slugged one of the monsters ( btw he found a broken piece of pipe) knocking it to the ground.
While Tsume and Jake were fighting Cheza ran to the fire alarm and pulled it so that everyone would evacuate the building.
