Ever walk through a spider web where there should not be one?

Ever brush at your face and come away with nothing?

The Dre'le'exx have been marooned on this planet for over four decades. Their mission: To purge societies of those deemed unfit. Watch what you think, because there is no such thing as a passing thought when monitored by these intergalactic exterminators.

Beware The Exoterrestrials.
