Syngorn is the largest elven city within the continent of Tal'Dorei.
Syngorn is built against the western base of the Stormcrest Mountains surrounding Lake Ywnnlas, and is surrounded by 40-foot-high walls of jade. All entrances into the city are warded by threshold crests depicting Syngorn's symbol, a crescent moon flanked by two trees over a cerulean stone. These stones anchor the city to the Feywild, allowing the city to transport to the other plane of existence in times of crisis.
Beryl Keep is the military district located on a hill in the northwest of the city, separated from the rest by walls of beryl. Within are the necessities to train Syngorn's military, the Verdant Guard, including barracks, archery ranges, and forges. Beryl Keep is commanded by Verdant Lord Celindar.
- Beryl Keep: located At the far northwest is the fortress after which the district is named. The keep's boundaries are marked by six ancient eucalyptus trees, which legends hold are treants who will animate to defend the keep in times of crisis. The keep is commanded by 
Looming over northern Syngorn is a mighty castle of faded marble covered in climbing ivy known as the Emerald Citadel. Located at the highest point of the gradually sloping city, the citadel's emerald-tipped spires can be seen from anywhere below. The Emerald Citadel is the domain of Syngorn's High Warden, Tirelda.
Considered to be the mind of Syngorn, the Memory Ward is built within a ring of marble walls on the northeast side of the city. A winding staircase called the One Thousand Steps leads to the district, which contains at its center the Sequoia of Remembrance, a three hundred-foot-tall redwood tree that mystically stores the lives and memories of every elf in Tal'Dorei. The redwood is tended by a group called the Dreamweavers, led by Ouestra, the Voice of Memory.
- Spires of Yurek: This academy is named for Yurek Windkeeper, founder of the Arcana Pansophical. The seven towers of the school are home to dormitories for the Dreamweavers, as well as many scholars who teach, study, and experiment with magic within its marble walls.
The Reverie Walks is the artistic and spiritual center of Syngorn. The district is made up of a shifting labyrinth of living trees and stones. Elves seeking meditation will wander through the Reverie Walks for hours in a trance-like state. No Warden holds sway over the Reverie Walks.
- Stone of the Archeart: At the center of the Reverie Walks is a column of pure diamond carved in the likeness of an androgynous elf. This stone is dedicated to Corellon, the Archeart, the progenitor the elven race. Many who seek enlightenment wander through the Reverie Walks seeking to find the Stone of the Archeart, but few find it within it's shifting paths.
Syngorn's central district is the Tarn Ward, a commerce district surrounding Lake Ywnnlas. During the day, the Tarn Ward holds no business save for inns and restaurants. At night however it it becomes a bustling marketplace, home to expensive goods of fine elven make, as the trade of common magical goods. The district's Warden is Guildrunner Rawndel, who leads the three guilds with which most businesses in the district are affiliated.
- Lake Ywnnlas: During the day, many magically propelled boats sail across the clear waters of the lake. By night, it becomes a perfect mirror reflecting the heavens above. On rare nights when the spiral-shaped constellation known as the Imprisoned is visible in the sky, spectral figures of starlight dance across the lake's surface, casting no reflection.
- The Feygrove: Once a large manor belonging to an elven noblewoman named Lady Il'shavfa, the building is now completely overgrown with plant life. Following the city's return from the Feywild during the Chroma Crisis, a small pocket of the Fewyild was seemingly brought with them. The manor is now teeming with fey creatures, and is ruled by a pixie prince named Windybranch. The fey who make their domain within the Feygrove have named it after the archfey who allowed them into the city, calling it "Artagan's Lodge".
Syngorn is a large city with a population of 37,030. It was one of the most homogeneous cities in Tal'Dorei, with the vast majority of citizens being elves (91%). The rest of the population is made up of humans (5%), halflings (2%), and other races (2%).

On 27 Duscar, 810 PD, a day after the attack of the Chroma Conclave, Keyleth performed a scrying ritual to check on Syngorn. She discovered a giant hole in the ground where Syngorn once stood. The members of Vox Machina believed that Syngorn had phased into the Feywild as a defensive response until the danger posed by the dragons had passed.
