Windweavers are Silvers who can manipulate the wind.
"Windweavers are elementals, able to manipulate air, usually to create intense wind or windstorms. Most skilled weavers can create air vacuums or even launch themselves greater distances using wind manipulation. In Norta, House Laris are windweavers duty-bound to maintain the military Air Fleet. Their abilities make them lethal pilots, using air-jets to conjunction with controlled winds." -Victoria Aveyard "War Storm" "On Silverblooded Abilities"
