The Spring Court was a group of important people in the Feywild. They hosted the Festival of Spring at their meeting place of the Castle of the Spring Court.
The Feywild Four were imprisoned near the Castle for various reasons before the Festival. They then broke out, with the help of Nook Nimmlock1, and brought the Jade Pyramid to Lady Arnaesis. She then used the Pyramid to trap the goddess Melora, and opened a portal to bring Lolth into the world2. The Court's fate, is unknown.
