The Hearts of Reptiles
Mezro is the religious center of the faith of Ubtao and the most populous city in Chult. The city is governed by a group of undying paladins put into place by Ubtao to guide and protect the city. At the city center is a great maze filled with deadly traps, dinosaurs, poisonous vermin, and man eating plants. The maze is used as a form of judgement passed on those worthy of life after committing some crime or blaspheme against the city or faith. Those who make it through are pardoned but those who do not are dead.
