Bifrost
The bridge between earth and heaven by which gods travel, also marked as breakable under later fire.

Overview
Bifrost is described in chapter 13 as the bridge from earth to heaven, bright like a rainbow. The text also says it is strong yet will break when Muspell’s sons ride over it. This account uses it as a passage for divine assembly and world structure without opening the full Ragnarok collapse.
