Vandarch

The Vandarch is an inland sea which constitutes the dominant geographical feature of northwestern Levantia. Bounded by many nations and fed by many rivers, the sea has played a key role in the cultures of its coastal peoples from antiquity to the present day. The sea was actually a lake until the completion of the Grand Vandarch Canal in 1975, having previously been isolated from the Kilikas Sea by the Pervalian Isthmus. It was also an endorheic basin until this time, as the construction of the Carolina Grand Canal caused the River Urce to flow into the lake rather than draw water out. Despite its historic isolation from the world's oceans and its relatively fresh water even after the completion of the Grand Vandarch Canal, the Vandarch was (and is) generally considered a sea by its inhabitants due to its sheer size.

Gothic
Two competing etymologies exist for the Gothic name Wandark, with both agreeing that the Wand element represents the Gothic word for "wall, barrier".

The first, chiefly propounded by Yonderian linguists, sees the -ark suffix as stemming from an East Gothic word with the meaning "surrounding/encompassing". Although not found in other Gothic languages, this particle is well-attested in the recorded history of East Gothic. In this theory, the complete name "Wandark" can be understood as meaning either "the encompassing wall" or "that [sea] which the wall encompasses", both in reference to the Vandarch being totally surrounded by land until the 20th century.

The second, favoured in Hendalarsk, treats the -ark suffix as an evolution of the Old Hendalarskisch word rak, meaning "straight" (itself from Proto-Gothic rakkjan, "to straighten"). Evidence for this can be found in the Werdacher name for the sea, Vandrakk, which apparently preserves the older form of the word. In this account, "Wandark" therefore means something akin to "the straight, walled [sea]", referring both to the sea's geological status as a lake for most of its history and the sea's relatively straight northwest-southeast orientation.

Both theories converge on the idea of the sea as enclosed by land rather than opening up into a wider ocean, a notion which implies a high level of seafaring knowledge among the Gothic peoples of the southern Vandarch coast well into the ancient past.

Gaelic
In the Fhainnin Gaelic mythos, the Vandarch is the result of the fall of an ancient god, though the name associated with this belief (English: Godsgrave; Fhasen: Déithaigh) has in part given way to a Fhasen reinterpretation of the Gothic name 'The Barrier' (Fhasen: Tá Bacain) following the Christianization of the Ninerivers region. The term 'Mar Déithaigh' has made a resurgence in recent decades under Faneria's government's cultural conservation programs.
