Hernipen Junction

Hernipen Junction is a nexus of several rail lines in the Howling Rails Campaign Setting. The junction is contained within a structure of several hundred feet in every direction, which sits aloft on a huge stone pillar in a world of clouds. The pillar fades away into oblivion beyond the clouds below. The air is perfectly breathable, and the structure is open to outside air. The structure is loosely built, with homes, businesses, and the railroad terminal built on the framework, and passages and steps outside.

Environment
The outside air is typically comfortable to briskly chill, ranging from 45oFto 80oF. It gently rains often enough to tend a garden, but storms and wintery weather are rare. The blue sky is cloudy or clear as regular weather patterns would have it, but miles below the junction is a solid sea of clouds.
