Warbler Island

Warbler is a totally silent island ruled over by Queen Eagala. The only reason she keeps it silent is to keeps everyone "safe" from outsiders. Years ago, when she was young, she went on a trip to find her brother because he and her sister went exploring and found hostility from other islands. When she returned from her journey, she found out that her beloved father, the king, had died. Then, Eagala would become the queen of Warbler Island. She wanted to keep her people safe and forced them to work underground and whisper. She cut any connections between other islands. When people rebelled because of being forced to whisper she stopped all talking by sewing thorns into their necks, forcing them to talk using sign language. And to make it even more quiet on Warbler, she cast a sound barrier spell that took sound away from the whole island, making even the waves around the shore soundless.

History of Queen Eagala
When she was young, her older brother and sister, Marcus Today and Justine left to adventure the world and never came back. She then left the island looking for them. She returned unable to find them, afraid of the dangers of the outside world and believing that enemies had killed her siblings. When she got back, her parents had died. As such, she was crowned queen. Immediately after that, she moved her people underground so that the believed 'enemies' would not target their island.

Because many people were unhappy with her actions, she placed a silence spell on the island. Then many years later, after people decided to escape and spread rumours about her island, she ordered the island surgeons to weave sound-restricting metal thorns into the people's throats once they turned ten. At this age, they also received drops in their eyes to turn their eyes orange, marking them as the property of Eagala.

Lifestyle
The people of Warbler have a horrible thorn necklace put on them when they turn 10, which doesn't allow them to speak. After the surgery, they are put into a dark cave for weeks until they are healed. As shown in Island of Fire, when Lani and Samheed are stuck there, they were feeling hopeless and in an extreme amount of pain which they eventually got used to. After the dark cave, they are given instructions and a working place and are required to work sunup to sundown with no rest at all. They also are connected to a long wire through their thorn necklace. If they prove themselves trustworthy, they get unhooked from the chain and are free to move around. If Queen Eagala fully trusts them, she takes off their thorns and gives them the privilege to speak. The instructors also frequently tell the people of Warbler that if they get their thorns off, birds will come and peck their eyes out. This warning ended up being false, as they were only saying that so no one would try to remove the thorns and spread what was happening at Warbler.

Additionally, every person at Warbler has orange eyes, marking them as property to Warbler forever.
