Mana Mark

A Mana Mark is a unique pattern or symbol that appears around the left eye of a sorcerer when they are using magic. Every Sorcerer (or Arcane Animal) has one of unique pattern and shape. It will glow in the color of the specific sorcerer's bloodline along with their eyes glowing a pale white whenever they are using magic. It will also give off a chime like sound as it shimmers, but this varies from time to time. Mana Marks tend to resemble a design similar to tribal tattoos or paisley like designs. Each mark will encircle the left eye and shimmer as the sorcerer uses their magic in various ways. There are similarities in Mana Mark designs between family members but always with variations. For example, Alistair Huntington's Mana Mark has a similar design pattern to his descendants such as Darla, Norah, and Isabelle Arrington. but each one is still a bit different. Its also shown that a sorcerers Mana Mark will usually resemble only one side of the family regardless of bloodline. For example, Isabelle and Nora's Mana Marks are very similar as mother and daughter who are the same bloodline, but Isabelle's mark doesn't seem to even slightly resemble her father Sebastian's. Yet shared bloodline does not seem to be a factor as Ashley is shown to have a Mana Mark very similar to her father Claud and yet Ashley is Ruby Blooded and Claud is Amethyst Blooded, showing that while the shape and style of a Mana Mark can be inherited from parent, a sorcerer's bloodline can be inherited from either the same or other parent. 
A Mana Mark is a genuine part of every sorcerer's body and always appears around their left eye. In certain practices of magic, a Mana Mark can actually be recognized and act like a form of spell signature. Such as how Sebastian Arrington was able to examine the enchantment placed on Chris Young to determine that it was placed on him by his father Nolan Young. This suggests that a sorcerer's magic is directly attuned to their Mana Mark thus the properly trained sorcerer can tell who cast any spell. Most sorcerers are also able to sense other sorcerers from a distance and can sense their Mana Marks with very little effort. While there are methods where a sorcerer can conceal themselves by suppressing their Mana Mark or conceal it so they can cast magic without any Nonbloods noticing this seems to require a fair degree of effort on the sorcerer's part and is not guaranteed to conceal their identity. No known form of magic is able to alter someone's existing Mana Mark and transforming into someone else does not change its shape or color. This is evidenced by Claire Dupont changing into Chris Young. While she became a convincing duplicate of Chris, she could not change her Mana Mark and still had her usual Gold one not Chris' Emerald one. While she was able to suppress it a bit so Isabelle couldn't tell off hand when she became suspicious and used her own magic to turn Claire/Chris' mana mark on the shape and color revealed her true identity. There has been one case of two sorcerers having identical Mana Marks in the case of Chris and Christina Young. This may be simply because they are (illegitimate) twin siblings, but Christina's unusual origins may also be at play. Either way no other sorcerers are known to have identical Mana Marks and no other Twin Sibling sorcerers have yet been seen. 
It has been revealed that there are practices of powerful blood magic that are in fact able to graft a second Mana Mark onto another sorcerer. Most notably Sylvana and Allistair Huntington using it to duplicate their own Mana Marks and graft a copy of them onto each other. While this apparently results in a tremendous increase in their magical power and potential it carries incredible risk of corrupting the souls who attempt it. The exact methods or process of this have not been explained. But the process seems to graft the second Mana Mark over the sorcerer's right eye and unlike their natural Mana Mark this one can be suppressed and concealed much more easily and doesn't always glow when the sorcerer is casting any spell. Its activation seems to mostly be optional.

* Its possible that a Mana Mark will also produce an arcane flame when a sorcerer is casting a Master Spell as seen in "Different Perspectives". When Dantelle is using Regeneration to create Christina's body her Mana Mark and Eyes glow but there is also a Green flame around her eye and unlike the purple flames seen in from Arcane Burning this does not seem to cause her pain and may simply be a sign of her Master Level Power being used.
