The dwarven races are quite diverse, but perhaps the most deviant, both physically and mentally, is the derro. Though seen as corrupt and malignant by most of their kin, derro perceive themselves as superior to their brethren. They scoff at their brethren’s naïve notion of blind obedience to kin and kith. For derro, it is power that should be respected and nothing else. Guided by this precept, the derro follow the powerful not out of any sense of loyalty toward them, but because it is from them that power can be derived. This will to power drives derro from birth to death in a never-ending struggle for personal glory and honor.
Since their inception, the derro have had to struggle against the sun. It has been an impediment to their will for centuries, but as time has passed they have found ways to circumvent the sun. Now, the derro prepare for battle with the world above and when it comes, a great lamentation shall raise from those of the world above as the derro press their foes both day and night. With cruel cunning they shall cause confusion and despair in their opponent’s ranks. They shall besiege their adversaries from above and below, they shall assault over and under the walls of their enemies. They shall slaughter those who stand in their way and enslave those who yield to them. Man, woman and child, human and humanoid, alike shall taste defeat and lie at the feet of their new masters.
Lurking just below the surface, derro have been, for most players and Games Masters, an unseen menace. This Slayer’s Guide shall remedy that situation. No longer shall derro be ignored as a race buried beneath the ground. No longer shall derro be an adversary caged in the caverns of the world below. No longer shall the sun keep derro from what is rightfully theirs.
Beware, good adventurers! For the derro are on the rise and you, my friends, are in their path…
