While Opal was lost in thoughts of how to make her illusionary world better, Karl was focused on the stones.
Their power was still present, undimmed by time. But they had gone inactive, and he couldn't understand the reason why.
The whole world was losing access to the system, and the power of the stones was dormant, but it wasn't losing any potency. It was more like it had lost its purpose, and was simply waiting for someone to wake it up again.
Mira sighed in resignation as she stared at the stones. "Well, if there is nothing to be done, then I suppose that's all there is to it. But it's good to know that this relic is genuine."
Karl nodded. "When you are ready to advance your class, or in need of something that the System should be able to do, try giving a prayer to the World Dragon while standing on the stones. If my guess is right, that should be the easiest spot in the world to access System features even as the System retreats from the world."
