The Slayer's Guide to Derro
This guide explores the derro, a deviant and malicious dwarven race that regards itself as superior to its kin. Derro society is driven by ambition, domination, and the pursuit of personal power rather than loyalty or tradition. It presents the derro as an active threat for fantasy campaigns, detailing their role as subterranean adversaries and bringing their hidden society and schemes to the surface world.
