The Dresden Files characters
Vadderung appears in "Changes" after being indirectly referenced numerous times by Sigrun/Gard throughout the series. He appears as man in his mid-50's with salt/pepper hair and a gray beard. He has an eyepatch over his left eye and has, in Harry's words, an air of power and authority about him. He provides Harry with much information on the location of his daughter Maggie and the purpose of her kidnapping, all while warning Harry of the danger he will face rescuing her. He demonstrates his power by casually pinning Harry to the floor with nothing but the power of his will rendering Dresden helpless. He is revealed to be the Norse god Odin.
