There are no flat hallways due to drainage in these often damp living quarters. The caves get drier as they get closer to the top of the cliff. Illumination is provided by low smoke candles and oil lamps, augmented during the day with window opening on the cliff face. Fresh water has been diverted from underground sources to pour through various chanels, fountains, etc and provide drinking and cleaning water for the elves. One cavern of note is the entrance from the sea, which is over a hundred feet high though much of it is underwater.
Various holes connect to the sea outside.
On the interior wall are wide sweeping stairs, where elves may sit to change from or to sea form. Lit by windows, there is also abundant low light plants decorating the cavern. They are 4 to 5 feet tall, very slender, and with pointed though small ears, however a few have large or exotic ears as a strong streak of shape-shifting has influenced varied family lines. Except for a few elves with strong foreign blood, they are amphibious with both lungs and gills-which are located in three slits along either side of the ribcage. After an ocean swim elves will head for the fresh water showers to rinse off, so their gills do not seal closed over salt.
