There was a slight tremor that Tilda could feel under her feet. It was almost unnoticeable, and anyone who didn't have a very sharp sense would not have even been able to notice that anything was happening. But since Tilda was so used to moving quickly, her feet were extra sensitive, and that allowed her to notice the tremor coming from deep within the earth.
Rumble~! Rumble~!
Tilda took a step back as the vibrations began to increase in intensity. Slowly, the people around the bar also started to feel the vibrations, and some of them began to stop what they had been doing to stare down. No one moved, and no one even dared to say a single word as they wondered what the fuck could be happening. And then the first tremor shook the entire city!
BOOOM!
