Tria was divided into four long time ago: Water, Fire, Air and Earth. All ruled by Aquarina, Blaze, Tempest and The Mother Earth.
Long time ago much before those Emperors all people was living in peace under one flag. That is... until earth benders show up. Their unnatural ways to bend the earth and incredible capabilities with fanatic followers lead to a chaos and a civil war between four kingdom. Such big chaos and war with unnatural ways have affected the humankind more than they could imagine.
War years are past centuries now. Four kingdoms Tria by four and live in harmony and peace. Old rivalries are yet to be forgotten but every nation have their own problems to deal with: Weavers.
Weavers were born generations later after the world war. Due to their mixed past and the radioactive effects of that war a bender can rarely be a weaver. Weavers can control specific two elements and combine them for divine combinations so they turn to be more powerful warriors than a normal bender ever can. A weaver can bend up to two elements which arent at their choice but in their nature.
Our characters' journey begins in a kingdom meeting each other on bending school. Mastering fire attunement in time and later trying to see if they can "weave" the elements in their own will (edited)
