Level twelve raised the stakes.
The world Elio now faced was a fascinating evolution of the previous one.
The eleven elements, the original ten plus the newly conquered phosphorus, had established a new and surprising equilibrium.
At the center of this evolved landscape rose the magnesium mountain, its surface shining with an intensity that made phosphorus's luminescence seem dim.
Where both elements met, completely new crystalline formations emerged, magnesium phosphates growing like mineral gardens, their perfect geometric structures defying the apparently chaotic nature of their surroundings.
The atmosphere had acquired surprising stability.
Magnesium acted as an invisible catalyst, dampening the violent fluctuations that previously characterized encounters between elements.
