After searching a while on old scripts i came across the 'Rovás' script.
Description from wikipedia:
Following is a image that we used to translate some of the script in Nidavellir:The Old Hungarian script (in Hungarian known as rovásírás, or székely rovásírás, székely-magyar rovás; for short also simply rovás"notch, score") is an alphabetic writing system used by the Magyars in the Early Middle Ages (7th to 10th centuries). Because it is reminiscent of the runic alphabet, the Old Hungarian script has also popularly been called "Hungarian runes" or "Hungarian runic script".The script is thought to be derived from the Old Turkic script, and probably first appeared during the 7th century. The Hungarians settled thePannonian plain in 895. When the Kingdom of Hungary was established in AD 1000 and Christianity was adopted, the Latin alphabet was adopted and the script fell into disuse. In remote regions of Transylvania, however, the script remained in marginal use by the SzékelyMagyars at least into the 17th century, giving it the name székely rovásírás.The script is adapted to the phonology of the Hungarian language, featuring letters for phonemes such as cs, gy, ly, ny, ö, sz, ty, ü, zs.. The modern Hungarian alphabet represents these sounds with digraphs (letter sequences used to write a single sound) and diacritics.The rovásírás alphabet does not contain the letters for the phonemes dz, dzs of modern Hungarian since these are relative recent developments in the language's history. The Latin letters q, w, x and y also do not have an equivalent as these do not stand for separate phonemes in Hungarian but are only used to spell foreign words.
The tall runes all around GH, and around the bear fort says:
"Big Bear Fort"
The Stone Plaque in the Helgrind Warren says:
The wisdom of the Sword
Strong steel can honor is the shield
win a warrior that defies
great scars but daggers and sways
honor with which swords - Honor is
he treats foes and wealth that cannotfriends will win be taken but is
him renown easily lost
The path leading down to the two doors in Nidavellir:
Better to walk slow and stand proud
Than to slip and look foolish and weak
(repeats every two steps)
The following translation seem to use a slightly modified script than the one used before.
it is called the 'Futhark' script, also known as A Runic Alphabet.
Futhark Script Description from wiki:
The runic alphabets are a set of related alphabets using letters known as runes to write various Germanic languages before the adoption of the Latin alphabet and for specialized purposes thereafter. The Scandinavian variants are also known as futhark (or fuþark, derived from their first six letters of the alphabet: F, U, Þ, A, R, and K); the Anglo-Saxon variant is futhorc (due to sound changes undergone in Old English by the same six letters). Runology is the study of the runic alphabets, runic inscriptions, runestones, and their history. Runology forms a specialized branch of Germanic linguistics.The earliest runic inscriptions date from around A.D. 150. The characters were generally replaced by the Latin alphabet as the cultures that had used runes underwent Christianization by around A.D. 700 in central Europe and by around A.D. 1100 in Northern Europe. However, the use of runes persisted for specialized purposes in Northern Europe. Until the early 20th century runes were used in rural Sweden for decoration purposes in Dalarna and on Runic calendars.The three best-known runic alphabets are the Elder Futhark (around 150 to 800 AD), the Anglo-Saxon Futhorc (400 to 1100 AD), and theYounger Futhark (800–1100). The Younger Futhark is further divided into the long-branch runes (also called Danish, although they were also used in Norway and Sweden), short-branch or Rök runes (also called Swedish-Norwegian, although they were also used in Denmark), and the stavesyle or Hälsinge runes (staveless runes). The Younger Futhark developed further into the Marcomannic runes, the Medieval runes (1100 AD to 1500 AD), and the Dalecarlian runes (around 1500 to 1800 AD).The origins of the runic alphabet are uncertain. Many characters of the Elder Futhark bear a close resemblance to characters from the Latin alphabet. Other candidates are the 5th to 1st century BC Northern Italic alphabets: Lepontic, Rhaetic and Venetic, all of which are closely related to each other and descend from the Old Italic alphabet.
Image i Used to translate this script:
I was able to use it to translate the white text on the half circle on the floor in Nidavellir main room:
(i'm not 100% sure about these translation, I'm not a native English speaker)
There are two sentences
on the half circle bow:
All they do is see the line of the portal falling to me, the commitment to take them the place among.
on the line:
Among the ninth halls of walhalla here the vow shall rest forever in time.
I hope you appreciate this.
I want to thank my friend 'Ronan Dawn' for assisting and veryfing bits of info.
