Deep beneath the earth, the derro wait in twisted cities built by their mad architects. These insane humanoids live, work, and somehow thrive in the lightless depths. They understand the truth about the uncaring gods that dwell between the stars, and they abandoned sanity long ago to save themselves. The derro hide within their insanity in the hope that the dark gods they fear will turn their attention to other, saner races first.
Despite the great distances between their Underdark cities and the surface, derro outposts can be found in the underworld and slums of many cities, both above and below ground. Occasionally, a derro discovers the wider world and finds a path out of the madness.
Pale and Stunted The derro are stunted, dwarflike humanoids, small of stature with wide shoulders and stubby limbs. They stand between 3 and 4 feet tall, with males only slighter taller than females on average. Their slender builds rarely weigh more than 40 pounds. Their pale skin is nearly translucent, revealing a ghostly web of blue veins. Their large, pure white staring eyes gleam in the dark.
Shorter than surface dwarves, derro are quick and erratic in their movements. Their elaborately braided or styled hair ranges from white to a pale straw color. Males take great pride in their prodigious mustaches, which are often braided and waxed.
Your derro character has certain characteristics in common with all other derro.
Age. Derro reach maturity by the age of 15 and live to be around 75.
Size. Derro stand between 3 and 4 feet tall with slender limbs but wide shoulders. Your size is Small.
Alignment. Their naturally unhinged minds are nearly always chaotic, and many but not all are evil.
Speed. Derro are fast for their size. Your base walking speed is 30 feet.
Superior Darkvision. Accustomed to life underground, you can see in dim light within 120 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.
Languages. You can speak, read, and write Dwarvish and your choice between Common and Undercommon.
Eldritch Resilience. You have advantage on Constitution saving throws against spells.
Sunlight Sensitivity. You have disadvantage on attack rolls and Wisdom (Perception) checks that rely on sight when you, the target of your attack, or whatever you are trying to perceive is in direct sunlight.
All derro are insane, but some exhibit more extreme behaviors than others. A variety of fetishes and compulsions affects this twisted race, and with the permission of the DM, the derro character is strongly encouraged to partake from the cup of madness.
These examples of insanity are meant to be roleplaying features, but the DM or the player may add suitable ingame effects by mutual agreement. A player can also invent other forms of lesser madness with the DM’s approval.
