Chapter 2... I think... It's short

Chapter 2
Wynn and Roan stopped at the gates of Aeden. They saw a tall man, looking sternly at the pair.
“Who are you?” he asked.
“We are centaurs from outside the city. I must take my son to one of your scholars for he stutters. I have heard that there is a man in your city that can help him… Please let us in… we will not be long.” Wynn said submissively.
The guard looked at her and then at Roan. He sighed and opened the gate of the city. Roan looked up at the guard. He had never seen a man before. The guard was tall and muscular, with dark black hair and a cruel weapon in his hand. Roan gulped. He hoped all humans were not like this. Wynn grabbed his hand and the two walked into the city.
The first thing Roan noticed was how busy the city was. He gasped at how many of these humans there were and how different they all were. They all wore strange coverings on their bodies. Some carried baskets full of food while others carried what Roan later learned was pottery. A young child threw a ball that hit him in the side, causing him to whinny loudly. Everyone stopped their activity and looked at the two centaurs in amazement. Wynn sighed and grabbed her son’s hand.
“Come, Roan. Stay near me…”
Roan nodded and walked with his mother through the streets. She took him down an alley where there was a small home. She knocked on the door and an older man came out.
“Demosthenes…” Wynn began. “Please help my son…”
The old man smiled and pulled out a bag.
“Put these pebbles in your mouth, and speak with them… do not stop doing this until a month has passed…” He said.
Roan cocked his head. He had no idea why this man was having him do this, but the man was obviously a scholar. Wynn thanked Demosthenes and left with her son. When they finally got outside the gate, she handed him the bag of pebbles.
“Now do as he told you. Then maybe the other foals will not laugh.” She said.
Roan nodded. He stuck the pebbles in him mouth.
“Mm-ma! Th-they tasth sthrange!” he said.
That’s because you’ve never had pebbles in your mouth…” she smiled.
The two began the walk back to the shelter of their cave.
