Arthosian

The Arthosian language is the first written language in Whirn. During the Golden Era of Whirn, there was a massive amount of scholarship going on in Arthosian, but almost all of it was lost in the sinking of the Great Forgotten City, now known only as Teifelheim. Due to the fall of the Arthosian Empire, almost all knowledge of the language has been lost.

Tomb of the Forgotten King
The oldest complete body of Arthosian text comes from an ancient tomb of an unknown king, which was found in Sfneed, the oldest known city in the world. The inscription reads:

''Tovou tolethi na xevetr heleis, ay keltenoy veretas yorum. Teweth ev sothoi fenebas callia.''

The only words which can be translated for certain are:

Tovou is accepted to be the 3rd person genitive pronoun

Heleis is the nominative form of "the sun"

Keltenoy is equivalent to "entrance," but is in an unknown declined form.

Fenebas is the nominative form of "fire"

Sothos is generally thought to mean "death" or "annihilation," although some scholars suggest it has more benevolent connotations

Ev is thought to be a preposition which directly correlates to the Mercer word "from"

Xevetr seems to be a verbal derivation of the noun xevet, which means "ice." The use of this word is likely colloquial in nature, and the best guesses as to its meaning in context all fall short.

And finally, teweth means "command"
