He is the real-life wizard headmaster giving Harry Potter's Dumbledore a run for his money.

Now the magic master has opened the world's only registered wizard academy, the Grey School of Wizardry, as he prepares to make Hogwarts and the world of Harry Potter a reality.

If you've ever read Harry Potter and wondered if wizards really do walk among us, perhaps behind a secret train platform, or in secret communities, I can tell you that we are absolutely real,' says Oberon, from Cotati, California.
 
platform：站台，月台
community：团体，社区
 
Today, Oberon Zell-Ravenheart's Grey School of Wizardry is the first wizard school to be officially recognized as an academic establishment.
 
wizardry：巫术
 
Like Hogwarts, the Grey School teaches 16 departments, including Alchemy, Beastmastery, Horse-whispering, wand-making and spell casting.
 
department：系
alchemy：炼金术
beastmastery：驭兽术
horse-whispering：马语
wand-making：魔杖制作

Pupils who attend unique "conclave" magic schools are split into four ancient houses - Winds, Undines, Gnomes and Salamanders, and like Potter, students study a defence against the deadly Dark Arts.

ancient house: 世家，望族，这里指派系
Winds, Undines, Gnomes and Salamanders：风、水、土、火
 
In the magic community I'm referred to as the real Dumbledore,admits Oberon. But before Harry Potter, people just called me Merlin, or Gandalf.

The former teacher and counselor was teaching spells to aspiring wizards long before JK Rowling even dreamed up Harry Potter.
 
counselor：顾问
dream up：思,创造
 
Oberon rose to fame in the early 1980s as an eccentric who claimed to have created the world's first unicorn. Unbelievably, the self-proclaimed "master of wizardry" created a single-horned creature, using minor surgery on a goat, that made front page news in America.
 
eccentric：古怪的,反常的
unicorn：独角兽
self-proclaimed：自称的
single-horned：独角的
creature：人,动物,创造物
 
The creature later toured America with a famous circus. "It's every wizard's dream to have a unicorn, and we achieved that,"says Oberon, who lives with his wife, Morning Glory, 63, a witch. In 1985, he organized a diving expedition in Australia and New Guinea to investigate the age-old mystery of the mermaid.
 
circus：马戏团
Morning Glory：牵牛花
witch：女巫，女魔法师
expedition；探险活动
mermaid：美人鱼
 
The Grey School boasts 735 students, of which Oberon claims 100 are under-18 "trainee Harry Potters." For now, it is an online college with regular physical wizard camps, where muggles can study seven years to graduate with a journeyman degree in Wizardry.
 
boast：吹嘘,自夸
trainee：练习生,新兵
journeyman：学徒期满的人，熟练工，熟手
muggle: a person without magical powers（麻瓜，即《哈利•波特》中不具备魔法能力的凡人）
