The White Walkers [Part 2]

Northern didn't know what to make of this; the spectacle itself caused his mouth to hang open in awe.

What was this?

How is this even possible?

They were walking on... the sky?

To be precise, it wasn't the sky, as the leader of the White Walkers had said. It was a bridge.

To put it in simple terms, they were walking on the sky; to be particular, the aurora's colors served as a sort of trekking bridge for them.

All the leader had to do was make a hooting sound thrice, then slam the bottom of his axe on the ground.

Immediately, they were enveloped by a pillar of aurora lights. Northern was shocked to see himself walking on a bridge of light.

He and Raven were guarded left and right, walking between the other White Walkers, with their leader in front.

The walk continued for a while; during it, Northern tried to observe the world below.

But the world below was obscured, blurred, and not much could be discerned.
