The Pyramid of Light is the most powerful spell that Malachite could perform, it has the appearance 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. Whether it truly has the power to rip apart the space-time continuum 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.
