Fresko

Fresko – The Ashen Sun

Fresko is a high-mass brown dwarf, straddling the boundary between failed star and true star. It shines dimly with a deep ruddy-violet glow, driven primarily by deuterium fusion in its core.

Its atmosphere is a turbulent tapestry of dark storm bands, swirling ash-colored clouds, and glowing hot spots, with temperatures ranging between 1,800–2,200 K. Methane and silicate clouds occasionally rise and disperse in its upper layers, giving it a mottled, storm-lashed appearance. Unlike a true star, Fresko’s light is not enough to banish the shadows—its glow is soft and sullen, casting a permanent twilight across the inner reaches of the protoplanetary disk.

Encircling Fresko is a broad, dusty protoplanetary disk, glowing faintly in infrared. The disk is dense with gas, carbon-rich dust, icy grains, and rocky fragments, slowly coalescing into planetesimals. Closer to Fresko, the disk shimmers with warm metallic vapors and silicate crystals, while farther out, snow lines divide regions where water, ammonia, and methane can freeze into solid grains.

Streaks and gaps in the disk hint at the early stages of proto-planets carving paths through the swirling matter. Jets of material occasionally arc away from Fresko’s poles, thin outflows of gas accelerated by magnetic fields, faintly visible as spectral beams of purple and crimson light against the darkness.
