Dwarvish

Spoken mainly by Dwarfs and called "uctu" is a language foreigners often percieve to have some resemblance of the sound of hammers hitting an anvil, or metal hissing while being quenched. The base rythm of the speech is undeniable and changes on wich topic is discussed. All in all the language is quite a hard sounding one and many percieve it as unwelcoming.
In addition to that the dwaarvish alphabet is a series of lines of various length, wich form the symbols and runes making up the language.
Dwarvish is the language mostly used to express complicated practical terms.
