In the cases of both Eldfyr and Hakida, they have enormous areas of wandering. There are times I couldn't find either one, but it turned out that I was merely missing an area of looking. Try walking around the mage's guild, the 'alley' between the fighter's guild and where the mage's guild area is, and also up and around the bank. Usually those are the best areas to find Hakida.
