Wind Weaver

Throughout history there are stories of unexpected winds that came to the rescue of fleeing ships. Most would consider this tall tales or mere luck. But there are those that swear the winds behaved unnaturally, and that they saw someone actually dance along the wind on those ships.
These stories carry truth in them, for rare Wind Weavers actually can control the wind. It is a slow act, requiring time to build up, and strong willpower, but they do exist. If the wind is barely wrong, it takes but a small weaving with their hands to make it flow as desired. But to make a wind completely turn, to halt it or to strengthen it, it takes time and a strong mind.
Great manipulations are made tougher by the fact that wind is very random. The smallest whirl in it can cause it to flow entirely different. This makes it hard to steer it, for a push can easily be too much or too little. This is why the ideal teamup is between a Wind Weaver, to manipulate the wind, and a Thread Walker, to sense whether the flow is going as planned.
