"Slate"

Slate - also known as Isabella Gray - is a sheepish white woman with bushy brown hair and a slight figure. She is typically seen wearing a grey woollen coat with a black furred collar, and playing with an iPhone almost subconsciously. She speaks very quietly and precisely, often hesitating to choose her words carefully. She tends to zone out a lot.

Nobody knows how long Slate has worked for Caleb Grief, but she's definitely been around a while. She's almost considered the "stereotypical Grief lackey" - devoted, brainwashed and submissive (at least when around Caleb). She quite clearly adores Caleb and would do anything for him, interpreting almost any response he makes to her as a sign of his mutual affection. It's not a healthy relationship, surprisingly.

Slate is one of Caleb's main mouthpieces when dealing with non-vampires. She will never name him or reveal her employer, acting as if she is the only important party. She tends to call herself Isabella Gray because she likes the name. Whether or not it's her original name is something she refuses to answer.
