Whispers are Silvers who can read and control the minds of anyone. They can also communicate telepathically and are considered as rare, dangerous, and powerful among the Silvers.
"Whispers are perceptors, able to manipulate, read, and sometimes fully control the minds of people within reach. As with others, the strength and depth of this ability depends on training and talent, with the strongest whispers able to fully possess all corners of an opponent's brain, reading their thoughts or controlling their actions without their opponent even knowing. Because of this innately nefarious nature of such an ability, the treatment of whispers varies within nations. The Lakelands, for example, undertook a policy of extermination within the last century. All whispers, noble or otherwise, were killed or banished from the Lakelands. Foreign whispers are not permitted to be within suitable distance of the monarch. Whereas in Norta, House Merandus is a valued part of the court, and the current king, Tiberias the Sixth, is wed to Elara Merandus, a talented whisper." -Victoria Aveyard "War Storm" "On Silverblooded Abilities"
