All adult bilachi are equally at home on land or in the oceans, and their society spans both domains with underwater settlements on the continental shelves extending down to depths of forty metres and towns and villages built above the water on the slopes of mountains and considerable distances inland. Nevertheless, their preference is to dwell on the coastlands where they can easily transition from water to air or visa versa. Individuals may have a preference for primarily dry or wet living which they label as "deep" and "bright" tendancies. The current incarnation of their civilization favours bright bilachi, with the main centres of power being the land based cities.
