Also known as the Mothercrystal. A pivotal deity in the plot of Final Fantasy XIV, she shares a name with the planet it takes place on. She opposes the destructive forces of Zodiark and initially appears to players as a floating blue crystal.
In the Shadowbringers expansion, she is revealed to be a primal. In Endwalker, she faces the Scions in her true form - a transformation of Venat. This appearance resembles a giant, ethereal woman with white or blue skin, blue eyes, and wavy white hair. She has several pairs of white wings including one on her head, one pair of head fins, and a halo (vertical by default). She alternates between three sets of weapons in battle, the most iconic being a blue sword, which is seen in the cutscene symbolizing Venat sundering the world and features prominently in fanart.
