The Dwarves are an ancient race of skilled forgers and blacksmiths who hail from the realm of Nidavellir ruled by King Eitri. They are close allies of the Asgardians, and after being asked by Odin to create the mighty weapon Mjølnir they forged it for him.
The Mad Titan Thanos at some point invaded Nidavellir and attacked the Dwarves forcing them to forge the Infinity Gauntlet for him to harness the combined power of the six Infinity Stones, in exchange for being spared. Thanos later betrayed and killed all of them except King Eitri who was spared though had his hands crippled by the Mad Titan. Later Thor , Rocket Raccoon and Groot journeyed to the realm to find Eitri and reinvigorated his spirit to forge a new weapon for Thor to kill Thanos - an axe called Stormbreaker.
Imir forced the Dwarves to create him a special axe which can match any opponents and break the fabric of reality. When Thor found out what Imir wanted, he battled and defeated him with his lightning strike. After his defeat, he lay on the ground in crisp from Thor's lightning.
The Dwarven race was completely exterminated by Thanos after he forced them to create the Infinity Gauntlet for him. King Eitri was the sole survivor of the massacre, and remained alone on Nidavellir.
The Dwarves are a very skilled and advanced race of smiths, able to create objects with properties that can be regarded as magical by the Asgardians, like Mjølnir, Gungnir, Hofund, Infinity Gauntlet, and Stormbreaker.
