An Advanced Creature Profile by Vincent Groth.   

The Orc Broodmother stands nine feet tall with tan to yellow skin, large prominent tusks, and densely muscled bodies. They are born from an orc fed the blood of Haltheris, can’t reproduce(themselves), and can exist outside of the horde but when fulfilling their roles need constant support. Orc Broodmothers are often decorated in heavy warpaint, tattoos, and jewelry as they often produce most of the Orks of a clan. When mobile they are easily identified from Urkreed due to their bright violet eyes, weight of raw magical power, and green splotches on their bodies. 

Orc Broodmothers are extremely strong with skin hard enough to stop blades not properly sharpened and maintained. Their bones are as dense as an Ogre and they naturally wield magic. Broodmothers can rearrange their organs to support many Ork and Goblin children, they are able to store male and female genetics, replicate them, and gestate most Ork and Goblin species. 

Orc Broodmothers serve as clan leaders and as clan mothers able to add teeming masses to the great Greenskin Hordes.  

Orc Broodmothers generally are immobile due to their often-large broods, though when unburdened an Orc Broodmother is a terrifying foe with no real weaknesses.
