Habbles are city-like divisions of a Spire, each with its own local governance and economy.
Information
Spire Albion - and presumably other Spires as well - are made up of many habbles, stacked on top of one another. They are square in shape, mostly made of spirestone and full of many houses and buildings.
It is possible for humans to access different habbles from inside the spire using ramps, although cats seem to be able to travel more freely. To travel, an airship must ascend or descend the spire.
