The Vida Line is the oldest line of Macht Witches.
They are combat orientated and use a manner of silver daggers and knives.
Their magic has been described as being 'painful' probably because of it's use to harm and kill.
The Vida magic can be used to incapacitate humans, being the equivilent of a hammer to the head. It can also be used to 'cloak' a witch, hiding her from vampires and their blood-bonded humans as well as regular humans. This works by causing the brain not to register her presence, effectivly causing invisibility.
They like all Witches can sense vampiric and witch auras. They can also send this sense into hyperactivity by specifically trying to sense other auras.
