Elven Mage

Elven Mage is a somewhat generic title given to several creatures seen in the Elven Temple at Underdark Exit area.
The creature represented in the InfoBox is an example of one of these five mages.
Practically all of these various creatures are plot animation purposes rather than used as an opponent or interaction by the party. They are not meant to be attacked.
Most of these creatures are removed by script (destroy-self) from the map when Elhan finishes his main dialogue and assigns The Elven City Requires My Aid questline. Some others just move off the map when triggered to do so.
A similar one remains with General Sovalidaas, though this one has limited dialogue and a different .CRE file (C6EXTR04).
