"Dwarves are short, stout, grumpy and loyal. They love digging, they're tough as nails, and they love to fight (D&D 5th Ed)."

Dwarf PHB5e

Dwarves are an extremely common race on Iyvis, having their own major factions and areas of land. They are much more willing to mingle with other races than, say, the elfs, but are still fairly secretive in their own cities.

These cities are usually huge underground structures, often built near mountains or deep underground far from other areas. The dwarves claim a major stake in the continents of Iyvis, but are content with the areas they hold.

There are no Grey Dwarves, or Duergar, on Iyvis, but there are Hill and Mountain Variations who usually keep to themselves.
