The Dhurlan are the largest Thannish ethnic subgroup, and, today, make up the majority of Eldara's population.

The Dhurlan people date back to the early Third Age, where they migrated to a region called "Dureth." Once there they settled there, the Dhurlan took over the ruins of the ancient city of Tekrit and made it into a thriving Thannish city-state.

Around the year 1148 of the Third Age, the city-state of Dureth grew into the Kingdom of Valdor.

Later, under the rule of Valden the Conqueror, Valdor would grow immensely and eventually control the entire Heartlands region

Today, the Dhurlan are largest and most dominant Thannish ethnic group.
