If you spend 1 hour befriending and feeding a Medium beast of CR 1/2 or less, you become its mounted guardian. The type of beast you can befriend this way is determined by your archetype, but must have an Intelligence score of 2, 3, or 4. The beast you are the mounted guardian of is your unusual mount. It follows you and is loyal to you, but it acts independently. Your unusual mount shares your initiative and takes its turn simultaneously with yours.

You are aware of your counterpart, of course. But more than that, you loathe them. You have started your adventures, at least in part, in order to find this person, remove them in some fashion, and take their place.

Have you located your counterpart yet? Why do you seek to replace them? Are they repugnant and you would right their wrongs? Do you seek to balance the universe? Or do they simply have the life that you were meant to have? What if you do eventually find them—and realize you have no wish to fulfill what was once your burning ambition?
