Cadmus Peverell (fl. 1214) was a pure-blood wizard, the middle of the Peverell brothers. Cadmus, like his brothers, was skilled in the magical arts, but personally was described as being an "arrogant man". Cadmus and his brothers were the inspiration for the The Tale of the Three Brothers and thus the original masters of the Deathly Hallows. Cadmus was said to have possessed the Resurrection Stone, though the exact circumstances of this are unknown.
Sometime early in his life, Cadmus fell in love with a woman, and the two were engaged to be married. However, she died before this union could take place. Despite his fiancée dying, Cadmus was able to father an heir; whether it was with this woman — and she died in or after childbirth — or with another woman, is unknown.
In The Tale of the Three Brothers, Cadmus was walking along a lonely, winding road one night with his two brothers. The trio reached a river too wide to cross under normal means, and conjured a bridge to cross it. At this, Death appeared before them, angry that they had so easily crossed a river that many usually die on while crossing. However, he pretended to be impressed, and offered each brother a gift. Cadmus, seeking to further humiliate Death, requested a stone that would have the power to bring the dead back to life, which Death provided for him.
Using the Resurrection Stone and death
Regardless of how the Resurrection Stone was created, Cadmus returned to his home with it and used it to revive his dead lover. However, he soon found she had not been truly revived; she appeared sad and cold, and he felt as if a veil still separated them. Driven mad with longing, Cadmus committed suicide so as to truly be reunited with his lost love.
The Resurrection Stone would go on to be set into a ring, which would be passed down through the Gaunt family, and eventually be turned into a Horcrux by Tom Riddle, a distant descendant of Cadmus.
Personality and traits
According to Beedle the Bard, Cadmus was arrogant as when offered a gift by Death, he chose an object that he believed would further humiliate Death. He was also incredibly devoted to his fiancée even after she died, as he tried to use the Resurrection Stone to bring her back to life, and eventually killed himself to be with her.
It is possible that Cadmus' true personality are nobler than his depiction in the tale, since the spirits summoned by the Resurrection Stone are capable of protecting its users from Dark creatures' influence such as Dementors. Also, the living are able to draw comfort and strength from the spirits of their loved ones, as was exemplified in Harry's case when facing Voldemort. Furthermore, the symbols of his brothers' specific creation (the Elder Wand and the Cloak of Invisibility) along his own are etched into the stone, meaning that he had a great amount of respect for his brothers and their work.
Magical abilities and skills
- Transfiguration: Cadmus, along with his two brothers, was capable of creating a long and stable bridge out of thin air. This was Conjuration and is a very difficult branch of magic.
- Owner of the Resurrection Stone: Cadmus was the first owner of the Resurrection Stone which would later become one of the famous Deathly Hallows. Cadmus used the stone effectively but was overly dependent of it, letting its powers bring about his own death.
- Magical manufacturer (possibly): It is uncertain if Cadmus actually obtained the Resurrection Stone from Death. Albus Dumbledore believed it was more likely that Cadmus and his brothers created the three Hallows themselves. 
The name Cadmus may have been taken from the legendary ancient Greek Cadmus, founder of the city of Thebes. In the myth, he marries the minor goddess Harmonia, the daughter of Ares. Harmonia later comes into possession of a beautiful necklace, but this item in truth is cursed and causes great pain among Cadmus's descendants (a possible allegory for the Resurrection Stone, the cause of Cadmus Peverell's death as well as the object of a curse many years later or to the Opal Necklace in Borgin and Burkes).
Also worth noting that, in Greek Myth Cadmus created life by sowing dragon's teeth into the Earth. This is somewhat ironic when one considers that, the Resurrection Stone he was given (or created himself), brings back the dead (thus "creating life" in a manner of speaking), and the final fate of the stone is to be buried in the earth and lost.
Behind the scenes
- The Gaunt family claimed to be descended from both the Peverell family and the Slytherin family; it is probable that the two bloodlines intermarried in a later generation.
- The House of Gaunt are direct descendants of Cadmus Peverell, so it is certain that Cadmus had at least one child in his lifetime. It is not specified if the woman he intended to marry was the mother, or if Cadmus had fathered children from a previous or later relationship. However, as Albus Dumbledore believed that, in reality, the Deathly Hallows had not been gifts from Death but rather inventions of the Peverells themselves. Given that there are no means for Beedle to know of what really happened, it is assumed that the account of Cadmus' death was simply fictionalised by Beedle.
- The chapter art from The Tales of Beedle the Bard shows that Cadmus committed suicide by drinking poison, whereas the scene from the Harry Potter and the Deathly Hallows: Part 1 film shows that he hanged himself. In the video game, he kills himself via a Killing Curse.
- In LEGO Harry Potter: Years 5-7, Cadmus is grabbed by Death along with his brothers taking place in his home but what happened to the Resurrection Stone before Tom Riddle is unknown.
- The fan theory that Cadmus made the Resurrection Stone is supported by how in The Tale of the Three Brothers, Cadmus knew to turn the stone thrice in his hand for it to work despite Death never telling him how to use it.
- There is also a fan hypothesis that Cadmus created the Veil in his mission to bring his fiancée back, but only succeeded in creating an unpassable pathway between the living and dead.

I borrowed it from Kreacher,” she explained as Ron raised his eyebrows. “It lists the pure-blood families that are now extinct in the male line. Apparently the Peverells were one of the earliest families to vanish.”"
