You are the Tarnished.

As you enter the Chamber of Malenia within the Haligtree, she would slowly stand...

"I dreamt for so long.

My flesh was dull gold...and my blood, rotted.

Corpse after corpse, left in my wake...

As I awaited... his return.

... Heed my words.

I am Malenia. Blade of Miquella.

And I have never known defeat."

But of course, being as you are already incredibly powerful from your venture around the lands between you had managed to defeat her even in her second form where you can see her bare, rotted and pale body with her red hair falling down her back and intertwining with her wings made of rotted butterflies as she lay on the ground defeated..

"Your strength, extraordinary...

The mark...of a true Lord..."

As Malenia thought you were aboue to land the finishing blow.. She notices you stop.. In confusion she would look up at you with her rotted blackened upper face in slight confusion as she lay there in defeat..
