T.D.o.N.B: S1J, part II - Overlord overload

I was expecting to be hit by some powerful attack, and even rushed to the side to get some speed, so it would be harder for him, but I actually never expected to be blasted from an entirely different location.

A burst of electrical energy fell from the sky, pushing me down. I somehow endured enough of it to create a barrier at an angle, that pushed me out of the stream before breaking, then I only went faster, trying to spot the source of the attack.

It was another overlord. This one though had a blue uniform and was holding a perfectly spherical orb in his hand. It was semitranslucent like made out of glass, but there was also something inside, giving at least part of it, in the very center, a slightly different color.

After his attack, there was a giant hole in the middle of the city. So vast that you probably could fit an entire district inside, and so deep that you wouldn't even be able to see it from the outside.
