Too much cliche-D&D for my tastes. As Moon said, too generic. There's no depth or backstory, beyond the fact that they may have been started by an Illithid. How did the come into being? Why are there two different types, and why the cost difference? Why do they use the methods they do? Flesh it out more, and I may change my vote. Go to Comment
It is just another uberish cult of uncatchable assassins. There is an attempt to make it more interesting, but it is not that differernt or interesting than the generic assassins organization. Go to Comment
What strategies do they use to avoid detection? How does one contact them? What role does the illithid play? GMs are supposed to be able to use this, so you need to provide the background details, not just what PCs might know.
Format wise, there are inconsistent capitalizations and spelling errors.
Using demons and summoned monsters to perform assassinations is a bit interesting, especially if the victims are PC's. Go to Comment
A military organization, the Stalkers are a hunting/mining militia that are known for wearing full body shrouds that easily hide them in snow and other slushy terrain. The lightly armored warriors are known for the speed, stealth, and the vicious wounds inflicted by their hunting hatchets. Many of the Stalkers keep crop-eared warhounds with them, both for hunting, companionship, and in war.
