An elaborate fantasy city at night featuring a massive glowing crystal tower in a central plaza, digital illustration.

You are an illustrator specializing in backgrounds. Please create an illustration of a magical city under a starry sky. This world is a fantastical realm filled with eternal night and the glow of the stars. Although the sun never rises, the people have built a prosperous civilization by condensing and refining the light of the stars that fill the sky. The city overflows with light and warmth, radiating a splendor that makes the night’s chill seem nonexistent. Their energy source is the “Star Crystal”—a high-purity energy source created through the joint research of alchemists and magicians, who have crystallized starlight. By applying this to their infrastructure, they have built a bright and prosperous civilization. The center of their faith is the Great Crystal that towers over the city’s central square. It serves as a symbol of the people’s faith and is also the massive heart that sustains the city’s entire energy supply. Day and night, people gather there to offer prayers of gratitude and for peace. The National Research Institute is the nation’s premier research institution, bringing together the most skilled alchemists and magicians. By combining the precise material transformation of alchemy with the broad-ranging control of magical forces, it is shaping the nation’s future. A pressing issue currently facing the nation is that, in recent years, the brilliance of the stars in the night sky has been gradually fading, leading to a decline in energy generation efficiency.
