Stopted at the gate

You make your way to the foothills of the Land known as Tripson On the side of the last mountain of the range stood a great human castle carved into the rock. This is where the king lives. You make your way up to the gate and a human guard stops you.

"Halt." The guard declares. He is several feet shorter than you as you stand 8.5 feet tall.

"What seems to be the problem?" You ask.

"Beasts are not allowed inside the keep. You will have to wait outside." The guard said.

"Excuse me! I am no beast. I have come to become a knight of this land and for that, I need an audience with the king." You explain.

"I am not sure if out king would want a creature such as yourself as a knight. Perhaps if you were to prove your self he might except." The guard replies.

You think to yourself: you could prove yourself to this king but there were plenty of kingdoms in the area and perhaps one would be less racist. On your way here you performed a great service lending help with the harvest in Lumos however that kingdom is too close to your home for your liking. If you become a knight there word would likely spread back to your farter. A Centaur Knight might be a big enough threat to leave his herd to deal with. You had also heard of a population of centaurs on the other side of the range living along the banks of a great river. You could find your own heard and live life naturally as a herd leader.
