Located on the four corners of Aggda are four colossal constructs. Each construct appears as a squat humanoid, 50' tall with massively broad shoulders. One arm of the construct points skyward and the other is held behind it, grasping a 8' diameter stone ball. It is believed that these constructs once defended Aggda against attackers and in times of great peril, could hurl the balls across the island, over mountains and into the sea surrounding Arcana. Legend has it that to hurl the balls great distances, the constructs would spin like a humanoid throwing a discus, thus the name Discus Constructs.
