The King in Yellow has a weird trajectory of appropriation from other authors. Carcosa comes from Ambrose Bierce's An Inhabitant of Carcosa, in the same collection of short stories containing a figure named Hastur. Concepts from The King in Yellow were borrowed by H.P. Lovecraft, and The King in Yellow was later turned into an entity called Hastur by Lovecraft-collaborator, August Derleth. The posthumous collaboration between Cosmic Horror and Fantasy writers of the day is pretty fascinating, and from a copyright/intellectual property POV, refreshing in its own right.
Coming up with a design for this was interesting- though the association with Lovecraft and Derleth's work is hard to distance one's self from, I tried to. There is no tangible description of the figure, so I mostly went off of the first-printing book cover that features a yellow robed figure with a strange crown. The heaping mass of tentacles are more or less the subconscious Lovecraft-influence.
I like what Terry Pratchet said, 'Pop fantasy is like a giant stew, the point is to add more than what you take out of the pot.' You can like an idea, and use it, but you need to make more than you take; that's what inspires future story tellers.
Nice! That is the most original take I had ever seen. Most would do a man robed in yellow, with that iconic mark, but this really captures its other-worldly weirdness.
I have an old Ral-Partha "King in Yellow" miniature in my collection., panted yellow for the sake of an old-school D&D setting called Carcosa. Sadly, it is one of my least impressive miniatures as it dwarfed to Hobbit-size by most of my newer, larger miniatures. (25mm used to be the standard back in the day, but "scale creep" raised that to 28mm or 32mm.)
Oh, and since we are talking about Robert William Chambers:
Along the shore the cloud waves break,
The twin suns sink behind the lake,
The shadows lengthen
Strange is the night where black stars rise,
And strange moons circle through the skies,
But stranger still is
Songs that the Hyades shall sing,
Where flap the tatters of the King,
Must die unheard in
Song of my soul, my voice is dead,
Die thou, unsung, as tears unshed
Shall dry and die in
—"Cassilda's Song" in The King in Yellow Act 1, Scene 2
"What I offer is a life time of truths, all of which will weigh too heavy on heart and brain. The vast loneliness alone will sway you to my cloister, the truth will imprison you in service. To others you will be a slave but to yourself you will believe me devoted for my existence was mortal before now. It was hard, it was ruinously sorrowed and in the light of my truth you will dedicate yourself to me out of love. Not fear. That is My Truth."
Cassilda: "Indeed it's time. We have all laid aside disguise but you."
Stranger: "I wear no mask."
Camilla: (Terrified, aside to Cassilda.) "No mask? No mask!"
