Dark Light -

He cleared the dust to reveal a sphere of obsidian. It was cold—impossibly cold—and it felt as though it were pulling the heat from his very fingertips. But as he touched it, the sphere began to pulse. It didn't glow with the amber warmth of the mining crystals. Instead, it emitted a violet, shimmering radiance that seemed to cast "darker" shadows than the surrounding gloom. This was "Dark Light."

(how does the "Gray" economy work)? Change the ending (what if the Dark Light was a trap)? Characterize the sister (what was her role in his journey)?

When Elias looked through the violet haze of the sphere, the ruins of the observatory vanished. In their place stood a towering structure of glass and steel, bathed in a blinding, natural gold. He saw people laughing, their skin bronzed and healthy. He saw green things—vast, waving oceans of emerald leaves that he had only ever seen in tattered picture books. Dark Light

He didn't hesitate. He smashed the sphere against the stone floor.

Elias was a scavenger, a "Lamp-Lighter" who risked the suffocating outer wastes to find forgotten caches of old-world illumination. One evening, while digging through the ruins of a subterranean observatory, his shovel struck something that didn't feel like stone or lead.

According to the legends of the old world, Dark Light was the inverse of the sun. It didn't reveal the world as it was; it revealed the world as it could be. It didn't glow with the amber warmth of the mining crystals

But the vision came with a price. Every time the Dark Light pulsed, Elias felt a piece of his memory slip away. He forgot the name of the street he lived on. He forgot the taste of the synthetic nutrient paste that kept him alive. He forgot the face of the sister he was scavaging for.
