It was a sunny Monday morning. Pragna walked into class 10A, feeling curious about the day.

On her desk, pragna found a strange, colorful envelope. 'To class 10A', it read.

Inside was an invitation, 'Join me at the old library, for a tale of mystery and history.'

Everyone buzzed with excitement. 'Who could have sent it?' wondered pragna aloud.

After school, the class met at the library. An old book lay open, glowing faintly.

Suddenly, the book's pages turned. A voice spoke, 'Welcome to the secrets of 10B.'

A ghostly figure appeared, introducing herself as the first teacher of 10B.

'I’ve watched over this class, and now you're part of its legend,' she said.

Alex bravely asked, 'What mysteries does 10B hold?' The room filled with whispers.

Stories of kindness, courage, and friendship floated through the air, surrounding the kids.

'Your deeds here will echo forever,' the ghost reminded them, 'Choose wisely.'

With a small bow, the figure faded away, leaving the class inspired and united.
