Conceptualizing a New Metaroom

Along with the Alkali Norns, I'm also in the early concept stage of creating an entirely new metaroom for Creatures Exodus, possibly to go with them. Currently, it's going by the rather un-creative name of the 'Sanctuary'. The idea is to include a number biomes (each with their own distinct micro-climates and ecosystems) contained in and around a mostly-dormant volcano that rises out of the ocean.

Stay tuned for terrible concept diagrams to follow!
