Ah, the allure of the Dark. What happens when a good girl crosses to the other side of humanity?

The Dark fractions involving Dr. Natalie Lambert postdate the creation of the original faction symbols, which left me with a problem: how do I symbolize a vampire Nat (for, as a rule, that is what "Dark" means in a Forever Knight context). In particular, how should I modify the NatPack symbol, which is a caduceus?

Two options immediately suggested themselves: replacing the stylized bird's wings with bat wings, and bringing the twined snakes to life. My first impulse was to do both. ( But my first impulse was not my final decision. )
