“It's called shadow-whispering. My shadow is carrying my consciousness so nobody can hear me except you”

Tam Song, in Book 4: Neverseen

Shadow-Whispering is a unique skill to Shades that allows them to spread parts of their consciousness via shadows. Like telepathically transmitting, a Shade is able to communicate with one or more elves, while silent to those nearby. It is described as sounding like somebody is whispering very close to one's ear. When shadow whispering, your shadow reaches out to the person you are whispering to.
