I don't know whether white necromancy was intended to be magic unique to mist elves, but I think it's fun to play neutral and even lawful necromancers. This flavor of magic seems especially well suited to dwarves (earthy), gnomes (e.g. Tolkien's Druedain sub-race), and--why not--the lesser elves. Please consider extending the possibility to other races, and/or allowing a way in the game for other races to learn this use of necromancy.

This would also give us more chances to play with the feature, and have a serious discussion over the cost/benefit of creating the statues.
