In my mind the traditional Dungeons & Dragons style Dwarf or Dwergaz from the proto Germanic were originally a slave race that rose up against their inhuman masters the Svartálfar (Old Norse 'black elves') & their original creators the Brimir. They formed their own kingdoms far away on other planes but there are still Dwarven kingdoms within Svartálfaheimr. The wars between Dwergaz & Svartálfar (Old Norse 'black elves') are legendary.
A dwarf, in the Dungeons & Dragons (D&D) fantasy roleplaying game, is a humanoid race. The idea for the D&D dwarf comes from European mythologies and J. R. R. Tolkien's novel The Lord of the Rings (1954-1955), and has been used in D&D and its predecessor Chainmail since the early 1970s. Lady of Hats artwork is awesome.
The Dwarves are seemingly a dying people but in some sense their not going extinct. They continue to wander across the planes seeding new settlements & other fortifications. But what the Hell are the Dwarves of legend doing on Cha'alt?! The Dwarven communities on Cha'alt are there doing the same things that they always have been doing kicking ass & taking names. But they also have been heavily involved in the demonic worm trade, doing many of the heavy duty enchantments for many of the scavenger tribes,subbing mercenary work in the desert regions, working many of the desert caravans, and living the life of adventurers.

But the Dwergaz clans & tribes have secret agendas & reasons for being on Cha'alt. Their ancient enemies the Svartálfar (Old Norse 'black elves') have been selling millions of slaves for mass sacrifices to the Great Old Ones. The Dwergaz clans & tribal elders have been looking to the alien control center known as Elysium.
There are rumors that the ancient enemies of the Dwergaz clans the Duergar evil & vile creatures who fell to the forces of chaos weilded by the the Svartálfar (Old Norse 'black elves') are now maintaing some of the alien machinery deep below the face of Elysium.
The Duergar from the Monster Manual II are still evil as they come!
The Dwergaz clans on Cha'alt know that the planet is in total peril & that there's a limited time frame on the planet. Many of the clan houses have gateways to other worlds already set up. The tremors caused by the California dimensional warp have been tearing bits & pieces of the fabric of the local space time continum.
