Yem Croome

Yem Croome is a vampire, and on the older edge of the age range that typically attends secondary school.
He's got a bit of a surly personality.
He and Katerina Valdu are in the same clan so they call each other cousins. It's probably somewhat accurate, but vampire familial relationships can be a giant mess so who knows.
The only one who is uncomfortable being in the remedial English class. He's mainly there to fill a section of his schedule, not because he needs to be there.
He is very pale, but lacks the thick eyebrows that most of the rest of his clan has.
