The First Bond
According to tradition, the first Defender formed a Bond with a mortal whose life was in danger.
The connection was unlike anything the Zephyrians had experienced before.
When the mortal eventually died, the Defender lost a feather.
The event established an understanding the Defenders still carry: protecting another life means accepting the possibility of losing something of yourself.
Over time, the Bond became one of the most respected responsibilities a Zephyrian could undertake.
