Heraldic Device of Eärendil
The focus in Eärendil’s device lies in the Silmaril of Eärendil depicted in the centre, radiating six light beams towards the edges.
In the dark corners the Moon in its phases is shown. The presence of Isil might reflect Eärendil’s destiny to become a Star, but it is also the only thing that prevents this device from being entirely symmetrical. This perhaps distinguishes him as being Half-elven.
The six light rays are accompanied by six others, that seem to go in the opposite direction. Thus, forming twelve “points”, a clear relatedness with Idril’s device is seen (Idril being Eärendil’s mother), which is reinforced by the shared blue background of the two devices.
