The Walker in the Mists was a golem made from mist by Lord Erlan Duirsar of Evereska and the Greycloak Hills.
The golem was humanoid in shape but appeared to be made of solid mist.
The Walker in the Mists had the same abilities as an iron golem but was not susceptible to rusting. Its body of "hard air" was very similar to the characteristics of a wall of force.
Around 1367 DR, this golem accompanied various patrols by the elves of Greyhome around the Greycloak Hills.
