Glamour, from Celtic mythology, is the faerie ability to change the appearance of things. Reseda doesn’t actually have faerie abilities; she just thinks of her vampiric abilities as “glamour” because it’s the word she grew up with.

Reseda (thinking): I won’t figure anything out if I just follow and stare at it.

Better cast a bit of glamour to keep the general population from noticing…
