The Good Masters are the ruling elite of the city of Astapor, one of the three cities on the eastern shore of Slaver's Bay, composed of slave-traders. An Astapori slave-trader, Kraznys mo Nakloz, sold Daenerys Targaryen 8,000 Unsullied in exchange for her dragon Drogon. However, she broke the deal and ordered her newly acquired army to slay the Good Masters and sack their city. All of the Good Masters present in the city were killed.
Petty Harbour – Maddox Cove is a town of approximately 950 people located on the eastern shore of the Avalon Peninsula in the province of Newfoundland and Labrador. It is nestled deep in the heart of Motion Bay, just south (approximately 15 minutes away) of St. John's. The present town is approximately 200 years old, though the site has been continuously occupied since at least 1598, predating the arrival of the Mayflower and making it one of the oldest European settlements in North America.
