Many of the haciendas of Mexico are connected (and, in fact, the vampire lords often form distant broods of their own). Some of these lords maintain a number of ghouls, and history has seen the birth of several thrall bloodlines.
One of these bloodlines — the humbly-named campesinos, or “farmers” — are prized for their tough bodies but pliable minds.
This bloodline is not tied to any one clan, and many of the patrón Damned share the ghouls with one another as favors.
Unfortunately, as of late, the bloodline has suffered a number of odd congenital defects: shriveled limbs, weak hearts, missing noses. Defective specimens are kept around to perform the most revolting or difficult tasks, but they are often castrated or genitally mauled so that they may not further pollute the bloodline.
