How was he supposed to know?

As panicked as Lex was about the situation, he did not lose his senses. He honed in on all the refugees and paid close attention to whatever they had to say. So far, none of them had a clear picture of what was happening.

Everyone seemed to be reiterating the same things. They had been hit by a power outage, and though some of them had backup generators, none of their devices seemed to be working. Due to this, there was a complete blockade on communication via any electronic devices. As a result, they did not know the extent of what the situation was.

What they did know was that there was a gargantuan vessel, or possibly multiple vessels parked in the sky above the planet. Though the massive vessel itself had not attacked yet, many of them witnessed many distant, smaller vessels approaching the planet.

Out of sheer panic they had escaped to the Inn, unaware of what else to do.
