The Killgon empire is ruled by a fierce and merciless warrior race. Their entire culture is based on bloodshed. And blood boiling, and drinking, and vaporizing. They have integrated blood into every aspect of their culture and everyday life. They love the color blue because that is the color of their copper based blood. Their flesh is also highly flammable. Which they are very proud of. Setting things on fire including themselves gives then the most joy. Unless they are setting blood on fire.
Their preference of weaponry is usually energy based. Rocks and pointy metallic objects are much too barbaric and uncivilized! All of their art is edible. That is mostly due to the fact that all paintings and sculptures are made from the dead bodies and other remains of their fallen prey. Which they stand back and admire for a few moments, and then proceed to consume it. There are no grocery stores or food courts at their malls, as the Killgon mind set is that each individual is responsible for killing everything they eat themselves. It is considered lazy and cowardly to eat something that is already dead and thus, is not a fresh kill.
