“There was a fountain in the center of it all, two golden figures standing in a round pool, holding hands as colored streams of water showered them from every direction. A shadow of a girl appeared between them and took off through buildings, shattering everything she touched before she dove into a sea of shards.”
The Unity Fountain is a golden statue of a human and an elf holding hands, located in the center of Atlantis. It symbolizes the unity between humans and elves and was built when humans lived in Atlantis, but it is also ironically the entrance to the pathway to Nightfall. It may be torn down and replaced with a statue of Linh, Sophie, and Keefe in the future because they saved the city (Atlantis), although it is not completely certain yet.
Although it might seem like the first time, Nightfall was not the first time that the Unity Fountain was mentioned–in fact, It was a part of a memory in Prentice's mind in Book 2: Exile (refer to the quote at the top).
The Unity Fountain is described as having two golden figures, an elf and a human. The Elvin statue is described as looking regal, in an elegant cape and circlet, with part of his hair braided back and the rest hanging gracefully past his shoulders. He holds a scroll, offering it to the human statue, whose head is bowed with gratitude. The human has rougher features and seems to be wearing some kind of armor, but instead of a sword, he clutches a long, etched scepter. Carved onto the orb at the end is Vespera's signature, making the whole scene less dignified, marking the spot where the now-destroyed Nightfall could be accessed.
