A unique product of Veroncor, middenstone is a mortar-like substance with the main ingredient of boiled and crushed carrion roaches – a deep maroon insect native to the Verone Delta that have adapted to urban life with shocking success.
Kept in a semi-liquid and foul-smelling state in large midden-vats, raw middenstone can be molded into sheets, bricks, or many other shapes. Allowed to cool, it has the same strength and hardness as wood but is much easier to mold and is relatively resistant to fire and rot. Middenstone is used for piping, bricks, siding, and is a relatively cheap building material.
Middenstone has a peculiar, somewhat sickening, violet hue, as well as an unpleasantly organic smell of tar, oil, and graveyards. The substance’s main disadvantage is that it weathers badly and thus buildings incorporating it need more upkeep than those of stone.
