The Memoirs of Istaborn Tiberfoot Chapter 1: Introduction, a harry potter fanfic

Istaborn Tiberfoot was a Hogwarts headmaster, who was the first person to travel through the Forbidden Forest, he also made a potion to cure several poisons.
Born in 1343 to Belinda and Aldon Tiberfoot. He was raised in the small wizard village of Stathford, a village nestled in a hidden valley far from any muggle civilization. Its exact location was unknown.
His parents wanted they're child to do much in his life, so they pushed him to do great things (as he was there only child). Ever since he could walk, Istaborn loved to explore. He was later quoted with saying "I was so fond of exploring, that I once ran off while my mother was walking me around the village. She chased me, but I somehow managed to end up several blocks away from her. Little did I know this was the first time I ever showed magic abilities."
When he turned 11 in 1354 he received his Hogwarts acceptance letter, and after getting his things, was off to Hogwarts school of witchcraft and wizardry. He was put into the Gryffindor house
In his first year he proved to be a very good student, excelling in all subjects. But what alluded him the most was the Dark (or forbidden) Forest. Being adventurous and very fond of exploring, he found himself pondering just what was in that forest and were it went.
When the students went to the forest to learn, he was always very excited to learn about plants and creatures that lived there. He also, when he could get away with it, explored the school.
When he got his first broom from his parents at home for Christmas in his second year he was overjoyed. He had been taught that first year how to fly, and he proved good at it. He finished off his first year with great strength only ever losing 5 house points. In his third year he tried-out for the quidditch team and made it in. He got the spot of seeker. He was a skilled player and good with a broom. His fourth and fifth year were fairly the same as his first three. He played quidditch won a championship and was a very good and smart student.
In his sixth year he became the Gryiffondor prefect. But the forbidden forest still alluded him, it was just sitting there waiting to be explored. And several times he wandered into the dark forest at night with only a wand in hand. He showed true bravery doing a thing like that. He was surprisingly never caught leaving at night. How he did it, is still a mystery to this day.
He graduated from Hogwarts and began living isolated in the woods for twenty years. He lived off herbs and fruit, and hunted animals for meat. He kept a garden and he always excepted wizard visitors. In his hermit like experience, he found a plant that cured multiple poisons if made into a potion.
One day he decided he should go to Hogwarts and attempt to travel through the forbidden forest. He sent a letter to the headmaster letting him know. The headmaster accepted his proposal. And Istaborn set out on his journey through the Forbidden Forest.
It took an estimated year to complete this feat. Though he spent a lot of time there, living, and exploring. He had no intention of just going in and then going out. Istaborn returned to Hogwarts in 1383 to tell them of his conquest of the Forbidden Forest. He returned to Hogwarts and in light of his achievement, and the death of the previous headmaster, he was appointed deputy headmaster. He became the Herboligy teacher until only a school year later the next headmaster died. Istaborn then became the headmaster of Hogwarts in 1385.
He proved a good headmaster, keeping the school in order, getting things done, and the typical headmaster what not. Even though he was a grown man he was known to sometimes join the first years in flying lessons and show them what he had.
An important thing he did was donate money to half-blood children. So they could pay for school supplies. He was head master for 106 years before he died at the ripe old age of 148 (extremely old for muggles but not uncommon for magic folk) in the year 1491. He died after accidentally consuming a poisonous mushroom. After that he was succeeded by his then deputy headmaster Edessa Skandenberg. He wrote a book called The Memoirs of Istaborn Tiberfoot. There are, to this day, no known surviving copies.
