Guys go back to the fact, that the bindings were originally created to bind thunderaans essence/power. I believe the hole world know that the earth ring raised thunderaan and made him the new windlord. I dont see why we shouldnt know that. We see shaman all over the world and we can talk with each other so it isnt a secret for the world, thunderaan is the new windlord!
So someone try to bind the essence/power from thunderaan the windlord or made the bindings before thunderaan was raised from the earth ring.
1. Who wants the essence/power from thunderaan the windlord?
2. Who tried to catch the essence/power from thunderaan as he was "dead"? Maybe someone had tha plan raise him and get the power but the earth ring was faster?
Or
3. We are all wrong and the bindings are a homage and no one tried to use them and it is just a drop...
