Here you have 3 wizard portraits I thought were fitting to the spirit of the game. They were 15 earlier, but I made some further additions after getting myself the BNW 3.2 patch. So some of there are thought for the new races there.
I would really like to see them in a map, but unfortunately I'm not patient and/or talented enough to make one myself. Still, I think these portraits will make a nice addition to the game. I'm especially fond of them. And I'm sorry if you think there is gender inequality: I'm a female so I generally create female portraits (so much for egocentricity)
None of the artwork is by me, they're merely images I found on the web.
