I have been temporary Guardian overseeing Nova City since your namesake departed. That does not mean I am in charge. A Guardian protects the city from the most dangerous threats and keeps the population safe. There are others in charge of the more political or criminal aspects.

While it is an important position it is not like that of a ruler.
