Before Gaia made a home for the living creatures on land, she started out with the depths first. The great bodies of water that traversed deep into her soul, beyond where the sun rays did not reach.
Deep in her veins, obscure metals and plant life dwelled, When the sap from one particular plant was mixed with another it created bioluminescence. The first light source.
Intelligent life below used this and incased it in a magic whirlpool, lighting their vast kingdoms.
These were called Loomas.
