Hogwarts and the Sorcerer.

A new school year had begun at Hogwarts. The Great Hall now had five tables instead of four, sparking heated discussions among the students. Harry, Ron, and Hermione also wondered why the extra table had been added. No one noticed the four new chairs at the teacher's desk, though the teachers knew their purpose.
Dumbledore walked up to the podium and the hall fell silent.

Dumbledore:
I am delighted to welcome you! This year, our house will host students from the Russian School of the Sorcerer. They are unable to continue their education at home, so please welcome them with respect.

He introduced the departments (faculties) and their heads of departments:

— Horse (black and white robes) — head teacher Ustinov Tikhon Nikolaevich.

• Yarilo (light blue) - head teacher of Vologodskaya Anna Demyanova.
  — Dazhbog (yellow-green) — head teacher Veniamin Viktorovich Orlov.
• Svarog (red-brown) - head teacher Gleb Gerasimovich Kulagin.

Each squad lined up in front of the fifth table. Dumbledore explained: Hors is renowned for success, Yarilo for freedom, Dazhbog for love and devotion, and Svarog for self-improvement.
The Hogwarts students animatedly discussed the guests, their rumored severity, and the names of their houses. The guests sat at their tables: Hors and Yarilo on the left, Dazhbog and Svarog on the right. The teachers took four new chairs.
The food arrived as usual, but the Hogwarts students lingered, watching the Russian students converse among themselves in Russian. After a while, Harry, Ron, and Hermione decided to quietly approach their table to strike up a conversation.
