Its story
Shine Supernova is a fist-sized sphere of clear crystal suspended inside three interlocking rings of dark, seamless metal. A miniature star glows at its center, its surface traced with golden flares that never repeat in quite the same pattern. Fine alien glyphs orbit the core like tiny constellations. In darkness it casts a warm, steady glow, and when handled it feels faintly alive with distant thunder.
Lore
Legends claim Shine Supernova contains a sun that can never die. The truth is stranger: it draws upon an inexhaustible extradimensional source of energy, though its ancient regulators limit how much power it can safely release at once. It can illuminate and sustain devices indefinitely, but it cannot create matter, food, or life.
History
The Helion Architects built Shine Supernova as the heart of a stellar observatory and power nexus. When their civilization vanished, the station went dark, but the sphere continued to shine. Explorers have carried it between worlds, mistaking its unending light for a promise that its makers might someday return.
