Dwarf (Dungeons & Dragons) based on dwarf
A dwarf, in the Dungeons & Dragons (D&D) fantasy roleplaying game, is a humanoid race, one of the primary races available for player characters. The idea for the D&D dwarf comes from the dwarves of 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. Variations from the standard dwarf archetype of a short and stout demihuman are commonly called subraces, of which there are more than a dozen across many different rule sets and campaign settings.History
The concept of the dwarf comes from Norse and Teutonic mythology.  In particular, the dwarves in the Germanic story The Ring of the Nibelungen and the Brothers Grimm fairy tale "Rumpelstiltskin" have been called "ancestors" of Dungeons & Dragons dwarves.  Along with giants, dwarves were one of the first types of non-humans to be introduced into the Chainmail game, the forebear of D&D, when miniature figures of varying sizes were used together in the same wargame. The dwarf in D&D is based on Tolkien's version of the dwarf.The dwarf first appears as a player character race in the original 1974 edition of Dungeons & Dragons, with a design that is strongly influenced by the dwarves of Poul Anderson's 1961 novel Three Hearts and Three Lions. This early version of the D&D dwarf is limited to playing a fighter, and can not progress beyond the sixth level. With the release of the first supplement, Greyhawk, in 1976, they were then allowed to play a thief with no level restriction. Beginning with the 1981 revision of the Dungeons & Dragons Basic Set, and continuing also in all subsequent revisions, demi-humans such as dwarves were treated as their own classes. Dwarves were only permitted a maximum level of 12 (compared to the Halfling's 8, the Elves' 10, and the human classes 36).  With the arrival of Advanced Dungeons & Dragons, the dwarf was returned to a player character race in the Player's Handbook (1978) and detailed as a monster in the original Monster Manual (1977). A number of dwarven subraces are presented as character races in the original Unearthed Arcana (1985).In 1989, the hill dwarf, the most common dwarven subrace, appears as a character race in the second edition Advanced Dungeons & Dragons Player's Handbook and as a monster in the Monstrous Compendium Volume Two. Dwarves are detailed as a race for the Forgotten Realms setting in Dwarves Deep (1990). Several dwarven races are detailed as player character races in The Complete Book of Dwarves (1991).  The dwarf appears as a character race in the third edition Player's Handbook (2000),  the 3.5 revised Player's Handbook (2003), the fourth edition Player's Handbook (2008), and the fifth edition Player's Handbook (2014). The arctic dwarf, gray dwarf, gold dwarf, shield dwarf, urdunnir, and wild dwarf are all detailed in Races of Faerûn (2003). Dwarves are one of the races detailed in Races of Stone (2004).  The dwarf, including the dwarf bolter and the dwarf hammerer, appears as a monster in the fourth edition Monster Manual (2008).
