|Fate||Listening to Bilbo Baggins' story during the party.|
Born in TA 2990, Isabella Brandybuck was a member of the Brandybuck clan. As a child who grew up in Buckland, Isabella would often play along with her friends by the Brandywine River and pretend to go on adventures outside the borders of Buckland. Although her family had forbid her to go and would sometimes be punished. Isabella hated been punished and been told what to do since she had been fond in learning how her distant uncle Bilbo Baggins had left the Shire and ventured far to the east of Rhovanion. Isabella was skeptical and she often visited Bag End, and wanted to know much about Bilbo's adventures.
Later on the 22nd of September TA 3001, Isabella and her entire clan were invited to attend Bilbo and Frodo Baggins' birthday event. At around nighttime, Isabella was among the children that gathered around and listened to Bilbo's story on how he and the company of Thórin Oakenshield were captured by a trio of Stone Trolls. Isabella was really excited in wanting to hear the tale and was quite shocked on how the trolls would die from the sunlight and been turned to stone at the same time. She was later present while everyone cheered and asked Bilbo to make a speech before he blew out the candles from his own birthday cake. However, the speech ended short when Bilbo used his magical ring that he kept for almost 60 years and disappeared in front of the horrfying crowd.
After the War of the Ring was over, resulting the death of Sauron and the destruction of the One Ring that was casted back in the fires of Mount Doom in Mordor, Isabella loved to hear tales of Meriadoc Brandybuck, her relative, and of his journey with the Fellowship of the Ring. During the Fourth Age, Isabella began to read and write a book of hers when she was given old maps from Samwise Gamgee, who had recently took over Bag End after Frodo and Bilbo ventured west to the Undying Lands. For years, Isabella left Buckland and ventured east towards Rhovanion, a region inhabited by Dwarves, Elves, and Northrons.
