*Gasp* That blackness... The horns... Those pale sigils...! He's... The Lord of Shades...! He who unites The Void, the power opposed...!

oh is THAT what I drew! I was given refs of that guy but I wasn't really sure what I was drawin' hehe

Indeed it is! Deep below the kingdom of Hallownest, there exists a place where the air grows still... A colossal, empty abyss sits at the feet of the dead kingdom... At the very bottom, there is nothing. Nothing but Void itself and faint remnants of a civilization that once flourished. Black tendrils violently lash out from the depths and ghosts draped in their very own essence linger aimlessly over their corpses, like servants without a purpose. Then, there is a successor. He who bears the halves of the Pale Wyrm and White Lady and recalls his past reforms the reunited halves into something new. A title. A title and status that allows he who holds the Voidheart to unite the Void. "Lord of Shades" The one who unites the power opposed, an empty, terrifying god of gods with a body wrapped in black, with many horrific horns, eight piercing white eyes, and four destructive arms, capable of consuming The Radiance, banishing her to black purgatory. If the Shade Lord ever manages to influence a bug, it has been said that their eyes turn black, empty, and hollow, while their tears become black stains that streak their face.

...ah! Lovely context!
