Behemoth A very large shaggy haired beast of burden, think of a cross bread of a manmoth and a rhino. Saggy hair all over no trunk or tusks but one big horn that is wide and curved. Before inventions such as the T-1 Tazer Tank these beasts were used to carry around heavy weapons like heavy blazer sticks and Dragon Egg catapults. They were covered with chain mail and a thick armor plating.
Dragon A wild stupid and vicious beast that was in ancient days captured and forced into serving as a fighter/bomber for various kingdoms. Riders had to carry a long goad to wack at the dragon's neck and snout to direct it. Some dragons went wold and flamed off their own riders. Almost extinct today because people have hunted them to exterminate because they are a mencae to all life
Unicorn A fast, agile beast slightly smarter than a horse, used to be used in the calvary before modernization.
