While he isn't quite as good at it as Aqua or his teacher and father figure, Eraqus, Terra is capable of sensing the Light and Darkness within a person's Heart. For the most part, it's relatively passive, though if he actively focuses he can sense a great deal about a person just from this--the balance of Light vs. Darkness, and whatever they might be feeling particularly strongly on the surface. He can also tell how strong the hearts of those he interacts with are. This leads to the most important thing: the actual permissions part of this permission post.

•  Can Terra sense the Light and Darkness within your character's Heart? If so, then-
• On a scale of 1-10 (One being pure Light, and thus very rare, while 10 is reserved for those with nothing but Darkness), where does your character fall? Do they have more Light, or Darkness? Bear in mind that numbers such as 1 and 10 are very rare, and only happen in special circumstances. If you feel your character actually merits being on either extreme of the scale, then tell me why.
• Just how strong a heart does your character have? (Note: Strength of heart equates to how strongly your character's beliefs and will are, and their willingness to defend those beliefs.)

• If your character doesn't have a Heart, or is able to mask the presence of such, will Terra be able to sense this?

While Darkness itself isn't evil, it tends to draw all the icky, power-mongering types to it, and as such has gained a rather horrible reputation by proxy. There are few friendly users of this chaotic element, the two primary ones being Riku, and Terra himself.

Darkness is born from the more negative aspects of a person's heart; anger, fear, hatred--all negative emotions have their roots in Darkness, and as such, Darkness-users often walk a very narrow line. While Riku and Terra arguably use Darkness with moderate success, they have lost something--their innocence. They don't look at the world in quite the same way as their friends and fellow Keybearers.

People with Darkness in their hearts generally have a reason for it, whether it is a deep-seated fear of loss, some form of jealousy or inadequacy that drives them, or any number of reasons that might leave a metaphorical 'stain' on one's heart. People with more 'negative' or 'cynical' personalities tend to have more Darkness in their hearts.
