- "For over a hundred years, Braavos hid itself from the eyes of the world, who called it the Secret City. Using a dye derived from a local snail, our captains stained their sails purple to hide their stolen Valyrian ships. Our merchants carried false charts and lied when questioned about their home port. Eventually, one sealord, our elected ruler, decided enough time had passed, and initiated the unmasking of Braavos to the world and to Valyria."
- ―Tycho Nestoris
Uthero Zalyne was a Sealord of Braavos.
During Uthero's tenure as Sealord, he revealed the existence of Braavos to the surrounding world, including the Valyrian Freehold. As restitution for the ships stolen from the Valyrians by the slaves who had founded Braavos, Uthero sent envoys from the Iron Bank of Braavos to pay the Valyrians. However, Braavos refused to pay for the slaves themselves. The revelation of Braavos' existence became known as the "Unmasking", and is celebrated annually in Braavos.
