In Norse mythology, Vör is the goddess of intelligence and wisdom. She is said to know the truth in every situation and encourages us to use our heads when it comes to things that need our attention. In Old Norse, her name translates to either "the careful one" or "aware, careful."
When we were trying to decide what to call the site, we stumbled across her name, and it just seemed like a perfect fit. Hence the name vörvault.
