Crescent Lake

Crescent Lake is a lake that lies in the Great Forest of Evasha and is in the vicinity of the royal capital of the Elf Country.

Background
Crescent Lake was identified as the Elven Capital by the Slane Theocracy. In that regard, it is safe to assume that this lake is under the Elf Country's rule.

The Magic Caster of Destroy Arc
The lake was briefly mentioned during the conversation between the Prime Minister of the Dragon Kingdom and queen Draudillon about the Beastmen invasion. The queen mentioned that if the Theocracy doesn´t give them help then they should seek the Empire's help, since if their kingdom falls the Baharuth Empire will be the next target of the Beastmen. Nevertheless, the Prime Minister remember Draudillon that the Katze Plains prevent an immediate attack against the Empire, and if the Beastmen took the detour around the lake they would attack the Theocracy first.

The Ruler of Conspiracy Arc
During a conference held between Cardinals, it can be noted that the Slane Theocracy had already built a forward base at Crescent Lake. According to them, the Capital of Crescent Lake should have been destroyed in a few years, but that plan was slowly going off-script.

The Half Elf God-kin Arc
The Elf King having killed the members of the Holocaust Scripture and retrieving his father's bow then retired back to the palace of the royal capital. There in his chambers he offhandedly commented to his concubine, Mugi, on her daughter's death and told her to prepare for bed to make another child. The news caused her such grief that the mother instead chose to leap from the balcony to her death.

Later Ainz Ooal Gown came to the Elf Country, decided to investigate the capital. He infiltrated the city using magic. There he was disappointed on what he saw as found it to be repulsive as it has an air of oppression due to the dense population, reminding him of his original world.

Layout
Based on its name, it is assumed the formation of the lake is in the shape of a crescent. The royal capital was the only settlement by the elves that was constructed without the forest’s cover. And built on the shores of the lake, on a flat land with broken forests. The reason as to why the capital was built on the flats, was because there was a giant monster in the lake that captured and ate any large monsters that came nearby.

Features
Royal Capital: The capital has many houses created from elf trees. The layout was not so different from a regular elf village, save for the size and population density. The city itself is made of thousands of interconnected trees, not so dissimilar to a forest. Trees all line up endlessly and all look the same, lacking signboards and ladmarks. Due to the difficulty in navigation, it is a city that is unkind to travelers as the layout of the city lack common sense and order compared to human cities.

Meadow: An open area with short grass that was made deliberately by the elves to act as a defensive point.

Known Inhabitants
There are likely elves living at Crescent Lake as it is a territory part of the Elf Country's domain.
