Psi-Snakes from Outer Space, an encounter

Here is an encounter I wrote but ended up not using, so figured I'd throw it out there maybe someone can use it. Enjoy!

On a cold and lonely night, a bright light is seen streaking across the sky over a small village.

What the villages saw as a shooting star is, in actuality, an alien spacecraft. A group of alien hunters have come looking for slaves. The aliens are reptilians with psionic abilities and advanced tech. They have come for human slaves and will march toward the closest village and begin rounding up peasants.

 The PCs just happen to be in the village on this fateful night, either locals or just spending the night during their travels.
