  We report on a recently introduced Functional Renormalization Group (RG)
Equation, and we apply it to quantum gravity in Lorentzian spacetimes. While
the RG flow is state-dependent, it is possible to evaluate state and background
independent contributions to the flow. Taking into account only these universal
terms, the RG flow exhibits a non-trivial fixed point in the Einstein-Hilbert
truncation, providing a mechanism for Asymptotic Safety in Lorentzian quantum
gravity.
