History:

(Bring on the Bad Guys: Loki (fb) - BTS) - Jonathan Nilsson was a popular baritone opera singer and recognized for his skills in the 1890s.

(Bring on the Bad Guys: Loki) - Manipulative Loki, caught in the machinations of Mephisto and servant Sister Sorrow, took on the task to murder a poor but creative Parisian musician in the same era. But Loki became entranced by the musician's street-side song and encouraged him to expand it, magically crafting a grand opera hall, the Palais Pandemonium, and summoning Nilsson to perform in the title role for what became "The King in Yellow" opera. Nilsson and the opera writer became very close; the singer lured and distracted the writer away from his writing process. Loki, focused on the story as was his nature, angrily chided the musician and revealed his true godly nature. The musician ran and inadvertently imbued the opera with his passion and soul. Eventually the opera's opening night arrived, but evil Mephisto, impatient with Loki, sent Sister Sorrow, who callously sent costumed Nilsson falling off a catwalk high above the stage. The musician writer wept next to Nilsson's dead body, but Loki spurred him to continue with the show. With Nilsson gone, Loki took over the title role in the triumphant and dramatic climax where the Yellow King stood revealed.

"The King in Yellow" is a direct reference to the milestone fiction by Robert W. Chambers from 1895; it is a collection of 9 short stories and a sequence of poems that range from supernatural and weird fiction, and end with romantic stories. The book is said to have been an influence on the master of weird fiction, H.P. Lovecraft. The first 4 stories are loosely connected by three main elements: a play in book form titled "The King in Yellow" that can drive readers mad, a mysterious and malevolent supernatural being known as the King in Yellow, and a strange symbol called the Yellow Sign. The second story in the collection "The Mask" is in part a story of love, art and revelation (reinforcing the implied romance between Nilsson and the opera writer). This story opens with an early "excerpt" from the fictional play "The King in Yellow":
  Camilla: You, sir, should unmask.
  Stranger: Indeed?
  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!
These lines are the triumphant closing scene of the comic's opera wherein Loki plays the role of the chaotic stranger.
Other "excerpts" from Chamber's play are included in the comic's opera lines, and Chambers' strange symbol is devised and incorporated in the comic's opera (mind you, a similar sigil was designed for the Yellow King roleplaying game). So, you'd think the name of the opera's author character in the comic would be Robert W. Chambers or an anagram or a character from the book or somesuch, but the opera's writer is never named in the comic (which has been an online criticism, given he's a main character). The only clue is the opera advertisement poster (see last image) where the name is partially obscured, something like "Art--- ----ewe" (Arthur something?). Any suggestions or solutions welcome.
Whichever, I do recommend Chambers' "The King in Yellow" as an early weird fiction piece. If you like Lovecraft and Ashton-Smith, you'll enjoy at least the first half of this collection. Support your local bookstore and grab a copy!

CLARIFICATIONS :
Jonathan Nilsson has no known connections to:


"King in Yellow" opera

The "King in Yellow" opera was penned by a poor Parisian musician (who is never named), but the young busker was the target of murder by Mephisto, who tasked the god Loki to kill him. Loki was fascinated by the story and melody in the musician's song, detecting even magic within upon first meeting the lad in 1895. Loki created the Palais Pandemonium, a grand opera hall where the musician wrote his opera opus containing bizarre and supernatural elements. Loki had the renown baritone Jonathan Nilsson brought in for the starring role. Nilsson was killed just before the opera opened, so Loki took over the title role in the triumphant opening night, although Loki killed the musician with Mephisto's dagger at the climax. The opera gained popularity and continued to be performed into the modern day. Because of the musician's intense storytelling for the  opera, his soul was forged with the opera, so while Loki did Mephisto's bidding, he did not deliver the lad's soul as Mephisto had wished (but not contractually specified).

   The "King in Yellow" opera is a direct reference to the "King in Yellow" play, an in-story element in the milestone fiction by Robert W. Chambers from 1895 (see Comments).

Palais Pandemonium

Delaying his murderous task given him by Mephisto, crafty Loki used Dwarven spellcraft to instantly create the Palais Pandemonium, a grand opera hall in Paris to lure in the poor musician who was Loki's target. Paris shifted at Loki's command, making its instant appearance unobtrusive. The Palais was the musician's domain where would live and work; there he met the baritone star Jonathan Nilsson of his eventual opera "The King in Yellow" and there it would be performed. However, Mephisto grew impatient and sent his servant Sister Sorrow, who maliciously killed Nilsson just before the opera's first performance. Loki took Nilsson's role in a triumphant opening night, although Loki killed the musician with Mephisto's dagger at the climax. It's unrevealed what became of the building.
