Danu wearing her crystal transmitter. During the time of the Drogheda Civil War, Princess Danu utilized a concealed communication tool known as a Crystal transmitter. While acting as a spy inside the Drogheda Citadel, she needed a way to secretly contact the Drogheda Revolutionaries, and this device allowed her to do so without being discovered. Danu wore the transmitter as a necklace, effectively disguising its true purpose.
