Ekrizdis: Who Built Azkaban & Was Worse Than Voldemort

Ekrizdis (also spelled Ekrizdiz, Ekrisdis, or Ekrizidis) was a
15th-century dark wizard who built Azkaban — not as a prison, but as
his personal torture chamber. Unlike Voldemort or Grindelwald, he had
no ideology, no followers, no grand plan. Just an island, Muggle
sailors to torture, and magic so dark that when the Ministry of Magic
finally entered his fortress after his death, investigators refused to
describe what they found inside.

The Origins of Ekrizdis

Almost nothing is known about where Ekrizdis came from. Some
historians believe he originated in ancient Greece or the Mediterranean,
based on fragmented references in obscure wizarding texts. No records
of his early life, family, or training exist. He appears in the
historical record only through the evidence of what he built and what
he did — and that evidence is grim enough.

What is certain is that at some point in the 15th century, Ekrizdis
found an uncharted island in the North Sea, invisible to both Muggle
and wizarding maps, and decided it was the perfect place to disappear
from the world entirely.

The Construction of Azkaban

Azkaban was not built to hold prisoners. Ekrizdis constructed the
fortress in complete isolation, weaving dark magic into its foundations
from the start. He placed concealment charms on the entire island,
rendering it undetectable and unchartable. No one knew it existed.

Inside, he conducted dark experiments of a kind that the wizarding
world had rarely seen. He used the fortress as a base to lure Muggle
sailors to the island, where he would torture and kill them. Not for
information. Not for power. Apparently for no reason other than
bloodlust and the practice of dark magic.

It was during this period that the first Dementors appeared at
Azkaban. Whether Ekrizdis summoned them, created them, or simply
attracted them through the concentration of dark magic and suffering
on the island remains unknown. What is known is that he bound them
to the fortress, and they stayed long after he was gone.

What the Ministry Found After His Death

When Ekrizdis died, the concealment charms he had placed on the
island faded. The British Ministry of Magic, suddenly aware of an
uncharted island in the North Sea, sent investigators to find out
what it was.

What they discovered was a fortress overrun with Dementors — and
that was described as the least frightening thing inside. The
investigators who entered Azkaban refused to speak about what else
they found. No official record was made public. Whatever Ekrizdis
had been doing in that fortress for decades, the evidence was
apparently so disturbing that the Ministry chose silence over
documentation.

Rather than destroy the fortress, the Ministry made a pragmatic
decision: they would use it. Azkaban became the wizarding prison of
Britain, with the Dementors already in residence serving as guards.
The horrors Ekrizdis had created became the foundation of the
wizarding justice system.

Ekrizdis vs. Voldemort: Who Was Worse?

Voldemort wanted to conquer death and purify the wizarding world.
Grindelwald sought a world order where wizards ruled over Muggles for
the “greater good.” Both were driven by recognizable, if monstrous,
ambitions.

Ekrizdis had none of that. No goals, no ideology, no followers. He
tortured and killed for no apparent reason beyond an insatiable need
to do so. The complete absence of motive is arguably what makes him
more disturbing than either dark lord. Voldemort feared death.
Ekrizdis appears to have simply not cared — about anything.

He is also the only dark wizard whose legacy literally became the
infrastructure of wizarding society. Every prisoner ever sent to
Azkaban, including Sirius Black, Bellatrix Lestrange, and Hagrid, was
held in a fortress built by Ekrizdis for purposes far darker than
imprisonment.

The Dementors and Ekrizdis’s Lasting Influence

The ethical debate around using Dementors as prison guards runs
directly back to Ekrizdis. He is the reason they are at Azkaban. The
Ministry of Magic inherited his dark creatures and chose to employ
them rather than confront the question of what they were and where
they came from.

This decision shaped wizarding law enforcement for centuries. The
soul-destroying nature of Dementor exposure — causing prisoners to
relive their worst memories indefinitely — was considered acceptable
for decades, until Dumbledore and others began publicly questioning
it. That debate traces its roots to choices made around a dead dark
wizard’s abandoned island fortress.

Frequently Asked Questions About Ekrizdis

Who is Ekrizdis in Harry Potter?
Ekrizdis was a 15th-century dark wizard who built Azkaban as a
personal fortress and torture chamber. He is mentioned in the official
Pottermore/Wizarding World canon as the original inhabitant of Azkaban
and the reason Dementors first came to the island.

Did Ekrizdis create the Dementors?
It is not confirmed whether he created them or attracted them. The
official canon states only that Dementors were present at Azkaban
during his time there. The most widely accepted theory is that they
were drawn to the island by the extreme concentration of dark magic
and suffering.

How did Ekrizdis die?
The cause of his death is unknown. He simply died at some point, at
which time his concealment charms faded and the Ministry discovered
the island.

Is Ekrizdis mentioned in the Harry Potter books?
He is not mentioned in the original seven novels. His story was
revealed by J.K. Rowling on Pottermore (now Wizarding World), making
him part of the extended canon.

Why did Ekrizdis torture Muggle sailors?
No reason is given in the canon. Unlike other dark wizards who had
ideological or strategic motives, Ekrizdis appears to have acted out
of pure bloodlust, which is part of what makes him uniquely disturbing
in the Harry Potter universe.
