Question 777 Total Electrical Failure - then what?

Despite all the redundancy, what would happen to a 777 experiencing total electrical failure?

Many systems are electrically powered, including flight controls. But if there isn't any electrical power?

If some major failure, explosion or other extreme event happened in a critical place, like in the MEC, which totally fries the electrical system - and renders all generators, RAT, batteries, and buses useless in an instant.

I know it is "impossible" with all the redundancy, but so was the triple redundancy on the DC-10 hydraulic systems - yet a single failure took out all three systems. So just for a moment, presume all electrical power is lost (apart from autonomous systems, like the engines, ELT, flashlights, Rescue 406 etc)

Aircraft is until the time of that event on auto pilot and in trim.

What will happen to
