A fenvaerja that is capable of adequately utilising both Lumen and Vesper casting techniques simultaneously. Known for their destructive potential, many fear the nevtnaedr and will try to eliminate them before they turn into a problem.
The easiest way to spot a nevtnaedr is the purple, bruise-like skin splotching that grows on their skin when they utilise their dual casting potential too much. These marks are temporary and fade with a little rest or time, but being spotted with them can put one's life in danger very quickly.
