The dvergar (or "dwarves" as they are often called by humans) are an ancient people thought to be native to the Dragon Spine and found frequently among the Iron Hills. Though shorter than a typical human, dvergar possess a robust frame and are a hardy people able to withstand harsh weather, difficult terrain, and the constant threat of goblinoid attacks. Skilled miners, masons, and smiths, dvergar creations are renowned for their craftsmanship and durability. Dvergar also enjoy a reputation as sharp traders and excellent soldiers.

Those who would do extensive business with the dvergar, however, must first earn their trust, which is no easy task. They are an insular, clannish folk known for being humorless and often dour. Those who earn the title of "friend", however can count on them as brave, steadfast allies with warm halls and some of the best brews to be had. Dvergar value their families highly and will risk any danger to protect a loved one. Thus, a favor, or insult, given to a family member is rarely forgotten. Dvergar frequently identify their clan affiliation in colorful tartans and intricate banners.

The dvergar love of fine food, metal, stone, and alcohol is well documented, as is their dislike of waterways and open skies. Dvergar seem to maintain passable relations with the Ælf, despite very different temperaments, and ancient pacts and rivalries are not unheard of. Dvergar despise the goblinoids, with whom they have struggled ceaselessly for living space, and will often attack them on sight. Similarly, dragons are regarded as an ancient and terrible threat to dvergar homes.
Well uhhh. Thanks for the info. that a silent "d"?
They're also alternately known as "dwergi" or "duergar", so I would say that no, it's a /d/ with a /v/ modifier. Like Dvorak.

In some forms of fantasy -- purely the work of modern authors, I should mention, and not derived from real folklore -- dvergar are the evil cousins of dwarves; they are similar to goblins in lust, wrath, and envy, and similar to dwarves in greed, gluttony, and pride. (Neither are particularly slothful.) However, in actual folklore, dvergar is just the honest Norse term for dwarven elf. Those who are familiar with folklore will usually know that "elf" just means any form of non-human fey being, something which the writers for The Elder Scrolls picked up on rather fiercely.
Yeah, Germanic mythology didn't have the strict lines you see in modern fantasy. So a dwarf, elf, and troll might all refer to the same thing. The duergar as "evil" dwarves is pure D&D garbage, much like drow seem to be a misinterpretation of "dark elves" aka dwarves. And don't even get me started on kobolds....

Fortunately, I am not sticking strictly to mythology, and my dwarves definitely have some Tolkienesque elements. I try to portray them a bit more as a believable society though, complete with individual strengths and failings.
