After hearing the news brought by Edward and Yang, the group assumes Rydia was killed by Leviathan. Luckily, unbeknownst to them, Rydia is actually doing fine. In fact Leviathan took her to his homeland; the Feymarch, also known as Land of Summons or “The Land that Lies Between” by the dwarves of Tomra.
The Feymarch. fey |fā|: derives from the Old English fæge (“doomed to die”) and carries the related sense “in an unusually excited state (like one about to die).” By an extension, the word came to mean “whimsical, otherworldly, eccentric,” perhaps from confusion with fay (a fairy or elf). This shift in meaning was noticed as early as 1950. Today the word’s original meaning is all but forgotten—e.g.: “An upsurge of book sales in cyberspace could have dramatic effects on the fortunes of the already fey and contradictory world of book publishing.” (Washington Post, Aug. 4, 1997.)
march |mɑrtʃ| |mɑːtʃ|: a frontier or border area between two countries or territories, esp. between England and Wales or (formerly) England and Scotland: the Welsh Marches.
Ruled by king Leviathan and queen Asura, the Feymarch is the place Eidolonds call home. The Feymarch is located in the Underworld which, as its name says, lies beneath the surface of the Earth. In order to reach the Feymarch the player must go through the Passage of the Eidolons, a dungeon that links the Underworld to the town where all the summons live.
Aside from its inhabitants, a peculiarity of the Feymarch is the passing of the time. The high number of supernatural beings and the strong aura of magic that enfolds the area causes time to flow faster. While Rydia spends relatively few time in the Feymarch she will be nonetheless affected.
Since both the Underworld and the Passage are filled with rocks and lava, special equipment is required. Ships must be built with mythril in order to stand high temperatures, which is why the party is able to reach the Feymarch only after obtaining the Falcon airship. The spell Float is also suggested to avoid damage caused by walking on burning grounds. In the Feymarch it is possible to fight both Asura and Leviathan, the Queen and King of the Feymarch, in order to gain two new summons for Rydia.
With her home town destroyed, the Feymarch becomes a second home for Rydia. It is a place where she feels at ease since, growing up in a village of summoners, probably made her accustomed to the presence of Eidolons. Leviathan and Asura take care of Rydia as if she were their daughter and, fighting-wise, she makes important progresses by becoming a better summoner and improving her black magic skills.
