Using the Orb of the Moons in Ultima VI requires knowing where to put it for which location. This can eventually grow tiresome, therefore below is a chart on which the various locations in Ultima VI are listed on a grid for where to place the Orb. Note that the locations for the cities are still valid in Ultima VII.

In Ultima VI, the Orb can only be used after asking Lord British what the strange stone is and how it works.
