Gothic Royal Podcast Cover

Create a 16:9 cinematic podcast cover in a dark, medieval Gothic royal style, similar to an HBO historical documentary poster. The scene is set in a dimly lit cathedral throne room, featuring black stone arches, two soaring stained-glass windows with pointed spires, intricately carved Gothic architecture, golden highlights under candlelight, and a color scheme of deep black and polished gold. In the foreground, a bust of an aged king is placed, draped in a heavy fur cloak and wearing a magnificent collar, facing forward. Behind his head is an intricate, oversized golden crown, forming a halo-like architectural diagram, but his face is obscured by a simple vertical brown rectangle, thus anonymizing it. Behind him, fine gold line art is incorporated, including the crown, a magnificent cathedral city, royal seals, parchment manuscripts with Latin-like script, and a crowded medieval court. To the left is a tall heraldic banner depicting a crowned lion and the crown symbol, and in the lower left corner are four seated courtiers, their faces obscured by small brown rectangles. Utilizing dramatic contrasts of light and shadow, a smoky texture, the grain of aged parchment, intricate engraving details, and luminous metallic gold lettering. Add three lines of text at the bottom center: Large Main Title{argument name="main title" default="Immortality beneath the crown"} Add a smaller subheading between two thin horizontal dividing lines decorated with arrows.{argument name="subtitle" default="From theological monarchy to the birth of the modern nation"} And a small trumpet with decorative patterns for the author/source information.{argument name="source line" default="Ernst H. Kantorovich, *The King's Two Bodies*"} The layout should be balanced and have a poster-like feel, with the title occupying the bottom third and the crown halo occupying the top center. No modern objects should appear in the image.
