Rescue

Altera. 

Althea and the others watched as the small fireworks lit up the sky with mixed emotions. 

It really wasn't much, as she didn't have much waste guns and gunpowder, but it was enough to alert the survivors. 

"It was really short though, I hope a lot of people saw it." Sheila mumbled, looking at the now dark sky with worry.

"There should be." Eugene said, "Considering that other than the moon, there are no other sources of light at this time. The contrast would be enough for at least a few groups to see."

"There will also be monsters, however," Eugene added, looking at Althea with apprehension. 

She looked at them, nonchalant about this issue. 

As for the monsters that it would attract, the expensive sentry towers should be able to deal with them.

"Let's trust my very expensive defense system." Was all she said, very vaguely.
