As an old race, a species that have been around for a very long time, the Anu have clearly defined cultural traditions that affect their thinking, their actions and their interactions with others.
They are deeply dedicated to sentience and the intellect, and as such live in inherently peaceful, hierarchical societies based on a deeply engrained sense of respect. They are logical, rational beings with very little emotion.
The Anu use their highly advanced technological development to further their knowledge and understanding of the world around them. For hundreds of generations, they have been soft spoken, and spend most of their time studying and researching.
