Lorethion was the capital of Aurebor. Anyone who visited Aurebor Dynasty for the first time by teleporting to Lorethion's zone portal would think that they had arrived in the middle of a gigantic forest instead of a capital.
The buildings were giant living trees with cavities within their trunks that provided a space for the elves to live in.
The trees' branches were so thick and long that they intertwined with the other trees around them, forming a network of roads high up from the ground. Their foliage adjusted naturally, allowing sunlight into the city when the temperature was cold, and blocking the sunlight when it was too hot.
The trees were like caring parents who took care of the elves whom they considered their children.
