Old Dwarven language

The Old Dwarven language was the earliest attested variant of the Dwarven language, and it is the second most attested ancient language of Artograch that was spoken before the Proto-Elven invasion of Artograch. It is still used as for religious purpose in the Dwarven religion, although with modernized pronunciation - this form is known as Temple Dwarven.

Evolution from Proto-Norlokian
Old Dwarven - or rather, its written form - was rather conservative seems to have not diverged much from its ancestor, though some differences still existed:
 * The affricates deaffricated, which crowded out the original sibilant fricatives  to the postalveolar region.
 * While the precise articulation of the seven monophthongs and four diphthongs in Proto-Norlokian was not known, and it was unknown whether they were coloured by neighbouring slender and broad consonants. In contrast, in Old Dwarven, it was well-documented that the palatalization of slender consonants and velarization of broad consonants mainly manifested itself in the colouration of neighbouring vowels, rather than actual audible palatal or velar offglides following the consonant.

Consonants
In Old Dwarven, each individual consonant came with two variants: Slender (palatalized) and Broad (velarized/pharyngealized).

Vowels
Old Dwarven had seven monophthongs - - and four diphthongs. Unlike in the predecessor language, Proto-Norlokian, these vowels were heavily coloured by the surrounding consonants.
