This city was carved into a small mountain range through a rather unusual method: The city's priesthood possess the power to create (or gather - exactly how they attain it is a closely guarded secret) a substance called yezû - a sort of green slime that can destroy any stone, even the strongest granite (prevalent in the vicinity of the city), leaving only loose powder, but which leaves metals and organic matter intact. The city's architects know the exact amount of yezû necessary to destroy any given amount of stone, and thus, with enough careful application of the substance, have hollowed out dwellings, caverns, and even whole palaces from the mountains. All this requires a through understanding of the arts and sciences, and Mewa therefore serves as a center of learning throughout the region.
