Kyoleth's Codex: Entry 3, The Elemental Nations
One of the worlds in the multiverse that appears most often. It also holds one of the most versatile fighting styles and energy in the multiverse. Oddly enough even though it has the most worlds to appear, Kyoleth hasn't chosen a Heroic spirit from it yet. This may change soon with the latest world that has taken Kyoleth's attention.
The Elemental nations are home to two types of fighters. The first are the shinobi, assassins who make use of stealth to kill their targets. Or if that fails, high level techniques that cause large amounts of devastation. The second are the samurai. Similar to knights that appear in other worlds. Samurai fight with honor and weapons, using chakra to enhance their bodies and weapons during battle.
The chakra of Elemental Nations is unique. A blend of physical and spiritual energy, chakra is one of the most versatile energies in the multiverse, second only to magic.
Chakra allowed the user to reinforce their bodies, increasing speed and strength. Cast illusions (Genjutsu). Heal others from all but the deadliest of wounds (Medical Ninjutsu). Cast various elemental techniques and create clones (ninjutsu). Summon massive creatures to aid them in battle (Summoning) Even use kanji to create various effects (Fuinjutsu).
The Hero for most versions of the Elemental Nations is Naruto Uzumaki (Sometimes Naruto Namikaze). The Elemental Nations has the highest number of versions of it's world that survive the onslaught of Chaos.
Many of the worlds that fall to chaos are caused by Konoha themselves. In many of these worlds, Naruto is executed or banished for doing his job. This often changes him and causes him to work with the forces of Chaos and destroy the Elemental Nations. Oddly enough, this is one of the only universes that has something like this occur. No other Universe has people nearly as stupid as this one.
