basically, I wanted make up fluff for my ork army to give them a paint scheme and I came up with this.
The Gorgulls are something like khornate orks, except they don't worship chaos. They do go nuts when they see-smell-taste blood. Spilling blood (of any kind) is something they live for, even more than the average ork. The Gorgulls go out of their way to spill blood, for example, their artillery doesn't shoot explosives, they shoot nailbombs. Also their warboss is given the name The Gorgull.
From a modelling standpoint, they like to paint things with blood, use it as warpaint, etc. etc. I want to make a battlewagon pulling something like Skrag's slaughter cauldron thingy.
