Blasteryberry Street is located in Mithicus.

In sometime before the mid-seventh century, a "really torched-out" old man with two gold front teeth and wispy gray hair fine and shiny as a spider's web in sunlight, used to have a shop on Blasterberry Street. Gathering rose marble from the southern valley area of Mithicus, he made talking statues.
