File:TerrainSpecial Quork.png Quork Crystals (or "Quark Crystals") are a type of Terrain Special - specifically one of the Minerals. They appear on the overland map as a group of blue crystalline shapes. Quork Crystals are found only in Deserts. Quork Crystals are fairly common on the plane of Myrror, and occasional samples can also be found on Arcanus. If the Quork Crystals tile is within the catchment area of a Town, that town will produce an extra File:Icon Power.png , added directly to the town's owner's Power level. This bonus is doubled if the town has a Miners' Guild present.
