Gnome Subrace: Cloud Gnome
Cloud gnomes are the gnomes most often encountered in the tallest mountains of the world. They make their burrows in caves and tunnels above the cloudtops, building cities shrouded in the high mists. Tethered together with terrifyingly thin ziplines, these cities are spaciously arrayed across clifftops and very difficult to notice for those don't know of their existence. Coming upon their homes can be quite the surprise for visitors, as gnomes swoop through the clouds dangling dangerously from gliders and balloons, but visitors are often rewarded for making the climb. Cloud gnomes appreciate the courage and strength required to reach their homes and enjoy throwing feasts to learn the histories of such journeyers.
