HC on Facial scent glands on skeksis.
Skeksis produce an oily musk(would probably be repulsive to humans) from various glands around their body, most concentrated on their head. Their facial glands are around the top and back of their heads, cheeks, mouths and under the jaw. They use these to mark territory(their personal quarters) and favorite items(or even gelflings). The more dominate the skeksis the stronger their musk and the more they mark. Everything stinks of the Emperor!
