Veil

The Veil can be conceptualized as a separate dimension, existing together with the "normal" dimension - connected yet separate.

Certain species (e.g Shadowfangs) are able to enter and see in the Veil, but species lacking this ability are unable to see beings and objects that are hidden in the Veil.

Energy can be drawn from the Veil even by species lacking the ability to manipulate it to modify or empower their magic, however, due to the unstable and volatile nature of this energy use without preparation (e.g channeling it through your own body or coming into contact with it) of this may come with certain adverse effects, most commonly death and/or insanity.

If properly executed altering a spell with Veil energy sacrifices a portion of the user's mana instead to shield from the adverse effects of the Veil energy. This method is used for spells such as the Ætherfire spells used by Fire Imp Nobles.
