Pyramid of Light

"The crest of madness swells, the vessel of misery grows insolent, they boil, they deny, they become numb, they blink and impede slumber. The crawling Princess of Iron, the Mud Doll ceaselessly hurls itself into the abyss. Unite! Revolt! Come back to earth and know your own insolence! Forbidden curse number six hundered and sixty six, Pyramid of Light!" -Malachite's incantation for the Pyramid of Light.

The Pyramid of Light is the most powerful spell that Malachite could perform, it has the appearence of a giant pyramid made from pure, white light that surrounds the intended target, trapping them inside. Malachite describes it as a 'gravitational torrent with the power to rip apart space-time itself' so it can be assumed that the person trapped inside would be ripped apart atom by atom. Wheather it truly has the power to rip apart the space-time continum is unknown as Malachite only states this when he is transformed, at this point he may be over-exaggerating due to his slow descent into madness. On the other hand, the Sorcerers were capable of defying reality itself so it isn't entirely absurd to assume that it can rip apart the very fabric of space and time.
