Wakfu x Male Hollow Knight Reader:

Plot:
Long ago, there was a powerful entity known simply as the Wyrm.

Wyrms were odd creatures comparable to Gods in terms of power.

A Wyrm has a single instinct, bring others under their rule and create an everlasting kingdom.

Wyrms went extinct a long time ago, but one managed to survive and shed it's large monstrous form in favor of a smaller one that would make leading a kingdom much easier.

The Wyrm's new form, the Pale King:

With this new form, the Wyrm that would soon be known as the Pale King formed a kingdom known as Hallownest and ruled it for many years.

However, it would not last.

All Wyrms had the ability of foresight and would receive visions of the future and the Pale King would began receiving visions he did not like one bit.

His kingdom falling, in ruin and forgotten to time along with an odd cube.

Immediately the Pale King began trying to take steps to avoid this future.

After many visions he found out that this cube was called "The Eliacube" and it was a powerful device forged from Wakfu.

The Pale King then began working towards the elimination of all Wakfu.

He eventually managed to discover the Polar opposite of Wakfu, something known as "Void."

A pit of Void was discovered under the Hallownest The Abyss"

Void is a black living substance that existed since the beginning of the universe.

Void had the ability to nullify Wakfu and would no doubt be instrumental in the Pale King's efforts to preserve his rule.

During his time ruling Hallownest he had met a Pale being known as the "White Lady."

The White Lady:

She would also serve in his plans.

She was his Queen and had an insatiable desire to procreate...to breed.

And breed they did.

They produced several large eggs and the Pale King tossed those eggs into the Abyss.

Those eggs hatched, millions from each Egg came forth and enfused with the Void.

These children became known as Vessels and would serve as a sort of counter force to Wakfu.

In addition to this, more experiments with the Void were performed including filling armor with the Void.

Kingsmould:

These were known as Kingsmould and only a few were made as binding Void to armor was a long and time-consuming process and they served as Elite guards.

At first things were going smoothly, until an incident occurred, an attempt at making another Kingsmould went wrong.

For some reason this Kingsmould was quite mad and desired to collect and preserve living things.

The Collector:

This failiur was chased out of the kingdom and left to wander the wilderness beyond.

The Pale King assured his subjects this will not happen again and that everything was under control.

It wasn't.

The Pale King tampering with the Void to such extremes had catastrophic consequences.

The Void was beginning to destroy his kingdom from the inside.

The Void while alive was not unified, lacked consciousness and corrupted all that came in contact with it.

Citizens went mad, Vessels went mad and randomly attacked civilians and Hallownest was crumbling.

The Pale King realized this and immediately had every single Vessel destroyed and tossed into the Abyss.

The Kingsmoulds were spared due to remaining obedient and loyal, it was only the Vessels who weren't under control.

However, The White Lady grew disgusted with her husband's actions and left Hallownest.

Despite being fused with Void they were still her children and she loved them.

Eventually, Hallownest fell and the Pale King's vision came to pass.

Hallownest was forgotten to time.

Feeling ashamed at the hand she played for causing her people's downfall all due to her desire to breed, she sealed herself away in a secret area.

The White Lady sealed:

In time, a forest grew around the area she was sealed further concealing her.

Centuries pass and while it is believed every Vessel was destroyed, that was far from the truth.

A few managed to escape and journeyed out into the wilderness.

Nearly all died however, the only one alive now is you.

You: (Note: You are human sized)

You are the only surviving Vessel, not that you know.

Since the fall of Hallownest you had calmed down and became an emotionless shell of Void.

You wandered the world for a while, until one day you came across a little village.

In this village you'd meet a little group, a group you'd end up accompanying on many adventures to save the world.

Along the way you begin to develop emotions and a mind of your own, as well as eventually take your rightful place as the King of the Void and the God of all Shadows.

You: (Future)

You as the Shade Lord:

Love Interests:

Amalia Sheran Sharm:

Yuma:

Your relationship with Yuma and Amalia started out like your relationship with the others.

Quite rocky.

Due to your emotionless nature you weren't one to show mercy to Foes.

If anything attacked you, regardless of reason, your automatic response was to kill it.

Even if they were weak and begging for mercy you'd end their lives without a second, not that you could think anyway.

This behavior made the others, especially Dally quite cautious of you, it didn't help that you couldn't speak at all.

You also had absolutely no Wakfu in you which was quite strange and unsettling to them all.

However, as you developed and began gaining the ability to feel, you changed.

You became kinder, more curious of the world and protected others even when you didn't have to.

These changes caused the others to warm up to you more and both Yuma and Amalia to fall in love with you.

It started when you all went to the City of Tears and helped the Ghost of Songstress Marissa find peace and put a stop to the Soul Master's twisted experiments.

It was during these events you first began showing emotions and this new kinder side.

From then on everyone helped you understand your new feelings and you got more talkative.

Well, you spoke by writing on a sign since you didn't have a mouth yet.

You grew closer to everyone from then on, especially with Yuma and Amalia.

The Last Eliatrope, the Last Vessel and the Princess of the Sadida Kingdom.

You all have a curious romance, but a genuine one.
