Lex was fighting a large skeletal monster the size of a mountain, quite enjoying himself actually, when something suddenly changed. It was not just Lex who noticed, however. Every being in the Mirage noticed that the very fabric of reality was trembling.
Lex lost the ability to control laws, and his tenet retreated deep within himself while even his instincts wanted him to turtle up somewhere.
His mind began working overtime as he thought, for a brief moment, that some Celestial level being had targeted him. Yet when he spread out his senses, he saw that everyone was affected, just in different ways.
For example, the other Henali forces also trembled as they felt an immense power spread across the Mirage, while the forces of Sanguis Pluvia were all reduced to dust. All of them. Simultaneously. Dust.
