An Arbiter's path in a dungeon

A beginning

On a sunny day, screams of pain and terror echos in the building. The victims were being cut down mercilessly into pile of flesh, unable to defend themselves, only begging for theirs lifes. However the answer for their pleads was the sound of a claw cutting through theirs body and nothing could save them agaisnt this fate.

Outside a woman wearing a black dress is currently on her chair, drinking her tea. With her closed eyes and her peaceful expression, she enjoys this moment. The sounds inside the building doesn't seem to claim her attention and even the smell of blood was not affecting her. 

Then someone in a business suit with a black coat approaches with a claw on the right arm covered in blood and stand at her side. He wears a mask and three vial with different liquids are attached to it.

??? : Lady Elise, the purge is complete.

She then puts down her cup of tea and stare the result of his work.

Elise : Good work Orion, the Sweepers will arrive soon to clean it up. Let me finish my tea before we return.

Orion : As you wish, lady Elise.

Orion stands still next to her without making a sound while Elise savors her tea. The smoke and fire coming from the buildings, the broken windows and the smell of blood are everywhere. A bloodbath happened here and none of the two seem to be bothered by it. After a moment, she gets up from her chair.

Elise : ... Let's go, Orion. I've finished my tea.

Orion : Understood, lady Elise.

??? : <Be careful, I'm detecting anomalous reading next to two.>

They both immediatly get in their combat stance and they saw some electricity and some distortion before them.

Elise : ... Do you see that, Orion, Mycelia?

Orion : Yes, I see it.

Mycelia : <What do you see? Somehow I can't see anything here except some kind of distorsion.>

Then the anomaly starts to take a form.

Elise : This look like a portal... Interesting, Orion, prepare for battle. We may have some unexpected guests.

Orion : Understood.

Several minutes passes, the anomaly continues to grow slowly taking form until...

??? : Help me!

Someone gets out of the portal, a man and run to them.

??? : Argh!

Orion prepares his claw to cut down the stranger approaching his lady.

Elise : ... Stop. 

Orion frezees and wait for orders from her.

Soon after, some kind of humanoids with green skins get out and pursue the man while some of them run aggressively at Elise and Orion.

Elise : Interesting... Another kind of nonhumans in The City. Unfortunately, only humans can live here so die.

The stranger gets behind them and watch how they fight with a tired yet excited gaze.

Elise : Pillar!

A black pillar appears before her and go straight to these monsters, decimating them however a few of them manage to get on the sides.

Elise : Fairy!

She raises her hand and a golden glow appear in her palm. Then some golden lacerations appears on her enemies and they are cut down to a pile of rotten meat. Orion moves at lightning speed and use his claw to exterminate everything not human, leaving no chance of surviving his attacks.
