Veil



The Veil (see below for other names and denotations) is the border between the Shadowlands and the countless worlds beyond the Shadowlands.

The Veil can be seen as a shadowy version of the physical world, and can be routinely visited as a spirit when player characters die and release from their corpse, unless they are in a zone in the Shadowlands.

Description
The Veil is a greyscale realm where souls of the departed linger until they are gathered by a kyrian to be brought to the Shadowlands. Kyrian Watchers known as Spirit Healers dwell in the Veil and appear to those who die to peer into the soul's inner self and evaluate whether they are ready to be dead. If the Watchers deem the soul ready, they will call forth a kyrian Bearer to come and bring their soul to Oribos in the Shadowlands. If they aren't ready, the Watchers return them to life. The Kyrian ferrying souls across the veil into the Shadowlands also ensures a steady supply of anima for all the realms.

The Spirit of Tony Two-Tusk describes the Veil as "all grey and dark, swirling clouds". While Uuna was in the Veil, she described it as dark and she was unable to see anything, though she could hear people interacting with her in the physical world. From within the Shadowlands, she could see the light of the naaru A'dal who was in the physical world, but it was so bright that it scared her. The moonlight at Lake Falathim allowed her to see a friend in the physical world.

Sometimes, the spirits roam the Veil without resting. It can be because their resting place wasn't complete, because of a battle in their resting place or because of the corruption of their resting place. To bring eternal peace to the souls, it is needed to destroy the source of corruption or by making a ceremony with items such as Tuskarr Ritual Object.

Spirits in the Veil can physically interact with objects and people in the living world.

There are various ways for the living to enter the Veil. For example, the Murkweed plant's toxins are so potent that it even fools the spirit, allowing one to temporarily enter. Inhaling certain incences are also capable of allowing passage to the Veil. It can also be seen with some devices and potions while being alive. Many not-dead mortals who visit the Veil do not return.

Time is perceived differently in the Veil. Salanar the Horseman, who inhabits the realm, mentioned that only a few days had passed for him between the war against the Lich King and the third invasion of the Burning Legion when it was really years in the living world.

While within the Veil, visions of past events may be seen.

World of Warcraft
In World of Warcraft, the Veil can be seen when a character dies. They can be resurrected by a Spirit Healer (or by finding the corpse of their physical body, though this may be just a game mechanic).
