Merlin was born sometime during the medieval era. During his formative years, he attended Hogwarts School of Witchcraft and Wizardry, and was sorted into Slytherin House. It is possible that he was taught by Salazar Slytherin himself, given the time period Merlin lived in. It is said that Merlin's wand was of English oak (though his grave has never been found, so this cannot be proven).
At some point in his lifetime, Merlin became a part of the Court of King Arthur, assisting him during his reign. He was the enemy of Arthur's half-sister, Morgan le Fay (also known as Morgana), a dark witch.
Merlin believed that wizards should help Muggles and live peacefully with them. To this end, he founded the Order of Merlin, an organisation which promoted Muggle rights, creating rules against using magic on them.
At some point, either during Merlin's lifetime or after his death, the Order of Merlin switched from a Muggle rights organisation to an award bestowed upon witches and wizards who performed a great deed at personal risk or contributed to the betterment of wizarding society in some way, a sign of the estrangement of the Muggle community from the Wizarding one.
Slytherin students at Hogwarts School of Witchcraft and Wizardry took special pride in Merlin — "the most famous wizard in history" — having been Sorted into their House. However, this fact is one that the other houses do not like to recognise.
Magical abilities and skills
- Magical Mastery: Arguably one of the most powerful wizards of all time, it can be assumed that Merlin was rich in learning and experience and that his proficiency and knowledge in magic was of a standard few had ever seen before and unmatched by any other witch or wizard in his time.
- Charms: Merlin's skill in using charms, bewitchments and enchantments are legendary, to the point of him being dubbed the "Prince of Enchanters", which speaks for his exceptional ability in this field of magic.
- Spell inventor (possibly): It was thought by some that the Disarming Charm had been a creation of Merlin's, although some (like Miranda Goshawk writes in Book of Spells) maintain that that spell was created in the 14th century by Elizabeth Smudgling.
Behind the scenes
- Merlin is a wizard featured in many British legends. Though he first appeared under the name Myrddin Wyllt (Merlin the wild) in Welsh literature as a half-crazed prophet of the forest, he is perhaps most famous as a central figure in the Arthurian legend. He is most commonly depicted as the adviser of King Arthur.
- As the legends and tales of Merlin is known both to Muggles and wizards alike, and Muggles have written about how Merlin is said to have been the child of a human woman who was impregnated by a demon, many fans speculates that Merlin may have been a Half-Blood wizard, and that his father may have been a fearsome Warlock using magic against Muggles and were so widely feared by Muggles that he was recorded in myth as an evil entity. However, as mentioned, this is just speculation.
- Some myths claim Merlin to be a Druid and/or raised among them. While yet to be confirmed, this may very well be the case of his in-universe counterpart, as the Druids's respect and veneration of nature and all of its beings fits very well with the fact that Merlin not only reportedly was chosen by a wand made of English oak, a wood known to have "an affinity with the magic of the natural world", in which he would be likely to have already established an interest prior to his Hogwarts years, but it would also explain his desire to promote Muggle rights, as learning about the philosophy of the Druids from a young age would have shielded him from being influenced by the common belief in the inherent superiority of pure-bloods found in Slytherin house, which would have been especially notable if he indeed was taught by Salazar Slytherin himself.
- One of the possible questions in the Sorting quiz at Pottermore mentions that Merlin marked his possessions with a mysterious rune. Since this is just a possible answer to a hypothetical question, it is unclear if Merlin actually used this symbol as his mark in historical canon.
- Albus Dumbledore, an extraordinarily talented and powerful wizard, resembled Merlin in many ways, such as the iconic long beard and prodigious magical skill. Both were "Muggle sympathizers", although Merlin's belief in the pure-blood elitism is unknown, it likely was the same as Dumbledore's.
- It is unusual that Merlin, one of the most famous proponents of Muggle rights and tolerance, would be placed in Slytherin, a house strongly associated with anti-Muggle views, although since he was such an ambitious person with all his plans for the Order of Merlin, it is not entirely surprising. Slytherins aren't necessarily evil or bad, nor is there any reliable information on whether or not the House of Slytherin actually held the same views in Merlin's time.
- In fact, the entire placement of Merlin at Hogwarts is paradoxical. Hogwarts was founded in the 9th/10th century, and while the early 9th century was the time the first records of the Arthur-myth were written, the actual myth plays around the year 500 A.D., meaning that the 'historical' Merlin in fact predates Hogwarts by roughly five-hundred years.
- Coincidentally, Colin Morgan, who plays Merlin in BBC One's Merlin, was sorted into Slytherin in Pottermore.

Notes and references
- ↑ Given Hogwarts was founded in around 993 A.D. and that Merlin attended it, he must have been eleven by or after the school's founding. So, the earliest date he could have possibly been born is 982.
