What should I name a fictional city?

I am trying to write a city, but I can't think of a name for the city in the story. It's like the capitol of the world. It's needs a dark, medieval, yet bright and creative and unique name. I thought of Ivandrale, but the Ivan part is too much like a person's name. Please, please, PLEASE don't use any people's real names. Please give me real suggestions, not 'Picklevail' or something stupid. Thank you.
