Chief: Y/n, are you willing to do anything to protect the Ryusoul key?

Y/n: Yes, chief. I'm willing to sacrifices my life to protect the key.

Chief: Very well, Y/n. May the Ryusoul guild your path.

Y/n nodded as the rest of the tribe crystallized him and sent him to Emerald Forest's cave.

~~~ a Few years later~~~

At the Beacon Academy, middle of the history class. Doctor Oobleck, who is currently teaching the history of "The Great War".

Oobleck: Alright, students! Can someone tell me about the great war?

After Doctor Oobleck asks the question, a student with bright red hair raises her hand, and spoke;

Pyrrha: It was about the continent that wants to rule over and cause civil war.

Oobleck: Good answer, Miss Nikos, but not quite there yet! Now anyone else?

The student with white hair raises her hand and spoke;

Weiss: It was about the political content that wants to take over the Vale and fight alongside Mantle.

Oobleck: Very good, Miss Schnee. But there a spot you missing.

Weiss: What things that I forgot to mention, Professor Oobleck?

Oobleck: It's "doctor". I didn't earn the Ph.D. for fun, thank you very much! As I was saying you miss the whole theories--

A student with black hair with red tips waving her hands as she tries to spoke;

Oobleck: Miss Rose, do you know the answer?

Ruby: I know! It's the legend of the dino knight!

Weiss: Who would even believe there are such things as "dino knight"?

Oobleck: Excellent, Miss Rose! How do you know about this "legend of the dino knight" in the first place?

Ruby: Well... my mother always read a bedtime story about the legend of the dino knight... and I do have proof.

Oobleck: Excellent! Can you show it to the class, Miss Rose?

Ruby: Oh sure.

Ruby then holds it in her hand and shows a key, a color of red, and resembles a knight and a device that has a dinosaur head.
