Castle Enclosed in Cosmic Sphere

A towering gothic castle with illuminated spires crowns a range of snow-covered mountains, all sheltered inside a vast transparent sphere suspended against a star-filled void. Dynamic magenta crystal formations surge across the sphere's surface like liquid energy, framing the composition and drawing the eye from foreground rocks to the distant peaks. Smaller celestial orbs drift nearby, including a luminous blue planet that hovers above the castle rooftops. Deep indigo and violet hues dominate the color palette, accented by the cool white of snow, the warm orange glow from castle windows, and sharp magenta highlights in the crystalline structures. Dramatic side lighting from a distant star creates lens flares and rim light that emphasize depth and scale across the layered mountain ridges. The overall mood is one of majestic isolation and quiet wonder, evoking epic fantasy illustration with surreal cosmic elements.
