A massive object floated in space.
From its appearance, it looked very much like a cube... pieced together from several long, bar-shaped blocks.
Since the spaceship Yawgmoth was on was heading towards the edge of the Solar System, the gigantic structure outside the porthole appeared to be of pure, see-through blackness. The only giveaway was the shimmer of its edges, indicating that at least part of the gigantic structure was transparent.
Yawgmoth understood at once. This was the Bifrost.
About nine huge, bar-shaped buildings connected with each other, ultimately forming such a thing.
A colossal structure measured in "hundreds of kilometers" in radius. Many parts of it were hollow, so it was lighter than a planet of comparable volume. In addition, humanity had mastered more complex technologies capable of using electricity to distribute the giant structure's own weight across its entire form with electromagnetic fields.
Farther out, huge photovoltaic panels generated power.
