Several of our drones flew out to scout the surrounding areas. They came from different directions which meant that they were being controlled by a few different people. My people hiding in safe locations providing eyes weren't enough so I made them bring a few 'flying eyes' for assurance.
The gymnasium was packed beyond capacity and it was burning as if a god of fire said 'FUCK THAT SPECIFIC BUILDING!!!' and ignited everything inside. If the people inside wouldn't die from being burned alive, they would die from inhaling the toxic fumes.
If they were lucky, they would've passed out just from the pain and trauma they experienced the first few seconds. If that ever happened, they would just die later instead of suffering the agony of being burned alive. However, it didn't take long for the conscious ones to try and push their way outside the entrance, trampling the weaker ones beneath their feet.
