Skywounds

Skywounds, sometimes known as 'Void Tears', are magical gateways formed by cavities in the Veil. Scholars believe that their chaotic nature is caused by the clash of opposing magical Essences, creating wild and supernatural storms in the vicinity that they appear. Skywounds were though to be natural phenomenons, until it was discovered that Lucius Black and his Red Crusade were responsible for manually creating them using ancient Apostate magic. After their defeat in 2-77-5, the Skywounds ceased to appear on the Mortus, however some that had already opened survived. Though many have been hunted, it is unknown if any remain beyond the reach of men.

Creation
The exact nature of the Skywounds has, and likely always will be, left to speculation and theory amongst Sorcerers. It is not possible to examine one close enough without being vaporised by the surrounding wild magic, swallowed into the vortex, or slain by the Void Aspects that pour from within. What little is known about the creation of the Tears was gathered by the Grand Senition, when they were forced to resort to dark magic, and open a tear of their own directly into the Mortem Apostarium. The requirements for such a ritual are as follows. It is unknown if there are more methods to performing it.
 * An unwilling human subject. The younger the subject, the stronger your connection to the Void will be.
 * A table or restraining surface of some kind for the subject to be bound to.
 * A long serrated blade, capable of slicing human flesh and bone.
 * A cauldron of boiling water.
 * Instructions on how to perform the ritual.

Summoning
To perform the ritual that summons a Void Tear, one must follow the instructions of a Sagilinus Opharum. There are no copies in existence today, authentic or any other kind. All recorded copies were burned by the Senition after the defeat of the Red Crusade
