"They are The Greys.
Terrifying masters of mental power and high technology, these aliens have plagued mankind for as long as there has been a mankind.
Learn their secrets, see their technology, find out what it will take for a group of Player Characters to make a difference in a world where the Greys are just one of the horrible things standing between humanity and it’s destiny.
See their ships, their weapons and their armor. Marvel at their world-wide and galaxy-wide operation of human traficking, and dare to hope that mere humans can stand against them!
All right, so they’re a little squishy in some spots - but they don’t let that slow them down too much.
They are the Greys. To know them is to know true fear.
