Hyouden Clan. Yokan.

The history of Hyouden clan begins with Koori clan and the paths separated only after Kaguya rebellion. Group of clan members felt dissatisfied of clans involvement in bloody affairs. Most of clan members, no matter their opinion, were forced to fight in bloodiest battles for the sake of Kirigakure and people, which were at one point persecuting Koori just like Kaguya. This group of members tried to separate themselves from Koori clan peacefuly but later had to flee because Koori clan leaders called them traitors and ordered to kill anyone trying to leave.

Leaving main island of Land Of Water, they fled to hidden island, where they managed to survive for some time, living peacefuly, as they always wanted to. In that island they managed to create village and live as simple people using their bloodline for practical purposes.

Always living in fear of being attacked, Hyouden clan members didn't forget that they were once proud shinobi and continued raising their children to be warriors, though this was only done in few noble families.

Koori clan never forgetting betrayal, managed to find Hyouden clans hideout and hesitating no longer launched an attack, which resulted in more bloody battles. Unable to defend themselves, from more experienced and greater in numbers Koori forces, Hyouden clan was totally wiped out. Koori clan, leaving only ruins of once prosperous village and dead bodies of their distant relatives behind, forgave betrayal, washed in blood. Hyouden clan didn't recover and was announced to be dead. As time passed, it was forgotten.

As only three living members of this clan remain, it is now considered dead.

Clan members have bloodline called Yokan and because of it, most of members have natural element affinities of wind and water.

This clan was once part of greater Koori clan, which was later responcible for Hyouden clan destruction.

Clan members grow and mature faster but reaching physical age of 18-25 they stop growing. At age of 35-45 they begin aging slowly.

The Bloodline limit of the Hyouden clan is purely elemental. This meaning that they are one of the few ninja in the world that on top of the regular elements that all ninja have an opportunity of access to, they can also access a singular advanced element. Members of this clan have the basic elements of wind and water, though some members may have only one of these elements. They can combine the properties and fundamentals of both to create the ice element. This is done by the wind chakras adding a chilled factor to the water chakras, causing it become an over all colder chakra. When exuded from the body, its heat level is to low to be liquefied water, and instead takes the form of solid ice.

Unlike Koori clan, from which Hyouden clan originated, Hyouden clan members didn't focus only around this singular concept of creating and manipulating ice. They focused on achieving balance among all three elements. User is capable of manipulating all three elements as they wish, without using hand seals. Ice created by user is generally very durable and difficult to break, taking an excessive amount of physical damage for most techniques, and is also, in contradiction to naturally occurring ice, displays a resistance to fire, though is not purely immune to it its melting effects.

Hyouden clan members chakra is cold and when used, rapidly cools surrounding atmosphere. This cold is one of clans signatures in battles. Clan members are adapted to constant cold and can endure low temperatures more easily.

They can then enter one of the mirrors and instantly transport to another mirror.

The technique requires a large amount of chakra to maintain, so Their movement becomes progressively slower the longer they maintains the mirrors. Roughly a B ranked amount every two posts.
