The Goddess Nira is a water Goddess related to all the other Gods on the moons. She bends water to her advantage. Nira originated from a tear of the moon that Elantris is located on. As the moon advanced, Nira aged, growing to be the powerful goddess she is today.
As she grew fond with the people on her moon she began to gift the people. Nira goes around to the people of her land, gifting them special objects that are personally assigned to them.
Nira’s powers are specially correlated to water. She can shape water to be out of its ordinary state. Nira can also freeze the water that she moves. She can send in floods and other natural disaster if she feels they are needed. Though there are many water power advantages, there can be dangers to it.
