Warlock of the Magus World - Iron fist

[Burion]

In this world, there were all kinds of creatures and strange phenomenons. In some region, the clouds covering the sky would turn into acidic rain. Some other places were even stranger, like the deep ocean where all kind of dangerous creatures would lurk in the darkness. 

However, this world was also home to a human civilization. Once, it was a civilization where everything revolved around magic, from farming to transportation.

Ever since the decline of magic era, all tools and artefacts left behind the magi of the magus plane were damaged or destroyed. More than ten thousand years passed since the moment, with countless of creatures taking back the territory they used to possess before the arrival of magi.

However, the legacy left behind the magi was no small, allowing humanity to keep some of their lands, now divided in kingdoms and empires. Although the number of magi had decreased dramatically, they had never really disappeared from this land.

In the centre of Boar Island, a magnificent territory where a prosperous town had been built. 

[Valeria]

It was both a historic testimony of two thousand years of history and dominance in the Western Continent, as it was part of the Greenhill Empire, but it also happened to be managed by one of three Major Noble Families that swore fealty to the Imperial Crown: the Steelguard Household.

Like all noble families in the empire, the Steelguard Household was capable of using magic. They were not known for being the strongest, as they were always inferior to the Fireheart Household, expert in fire magic. They were not as wealthy as the Longlost Household either, which possessed a longlasting legacy of alchemists which owned a monopoly over alchemy goods.

However, the Steelguard possessed something far more superior.

Strong family bonds, where every member would be hammered into a useful tool for the family. No matter the politics or differents, blood would always be valued over interests. Where its competitors were fractioned and suffered from conflicts, the Steelguards were like a monolith.

However, in one of the rooms meant for the secondary branch heirs, a youth who sought power over, had spent dozens of magical crystals, the currency of mages, into herbs, stones and blood of an adult demonic wolf.

Putting himself in the center, he had read in the family's library that it could allow him to make contact with a demon. Hoping to become stronger at all costs, he made this terrible choice to summon a low-rank demon.

Seconds later, he was grinning.

"Success", he muttered.

His eyes changed. 

His posture shifted.

His soul had already vanished, consumed by the demon who had begun possessing this new body. 

Only low rank demons would be able to achieve this, as the plane would put heavy restrictions over stronger beings. But low rank demons were usually not intelligent enough to trick humans into deals that would forsake their body. 

But the demon was different, infinitely different from its peers, for it was chosen by hell itself.

And worse still, it had succeeded in invading Burion with a perfect vessel.
