Ley lines

Ley lines (Japanese:レイライン)are a system recurring throughout the Wild Arms series, taken from esoteric ideas of energy alignments in between sacred places and landmarks around the planet where ley points (Japanese:レイポイント) would be located.

Wild Arms / Wild Arms Alter Code: F

In the original Wild Arms game and its remake Wild Arms Alter Code: F, the ley lines are recognized as a "network of power for the Guardians" which the villainous Metal Demons attack with the Darkness Tear to sever the Guardians' power in their quest to take over Filgaia.

Wild Arms 2

The Raline Observatory in Wild Arms 2 was intended by the screenwriters to be called the Layline Observatory, but was mistranslated when the game was exported to the west. Likewise, the four "Raypoint" dungeons -- Raypoint Wing, Raypoint Geo, Raypoint Muse and Raypoint Flam -- are meant to be called "Ley Point" and correspond to the four Aristotelian elements of air (called "wind" in the games) , earth, water, and fire respectively.

Wild Arms 3

Another dungeon called Leyline Observatory, now with its proper name, is explored in Wild Arms 3.

Wild Arms 4

The HEX battle system introduced in Wild Arms 4 utilized five types of ley points along the ley lines at which the player could use elemental magic and summon Guardians; red for fire and Moor Gault, blue for water and Schturdark, green for wind and Fengalon, yellow for earth and Grudiev, and a clear, uncolored HEX (which could be considered the ethereal quintessence) for non-elemental attacks, healing and Odoryuk.

Wild Arms 5

While the HEX system and ley lines return in the franchise's successive game, Wild Arms 5, there are different guardians that can be summoned with mediums, although the HEX itself can still be used for elemental damage.
