There was once 3 gods, Mnemosyne, Dionysus and Morpheus, all of which needed a helper.
Dionysus needed a helper to help him keep up with the rising demand for strawberries.
Morpheus needed one to stop himself from falling asleep during duties, so her created Narcissa.
Mnemosyne needed someone to help her remember things, because even the goddess of memories couldn't remember everything, so she created Nimue.
All the three gods decided they shall be known as The Three Daughters of Wine, Memory and Dreams, and gave them names, Bleu, Narcissa and Nimue. The girls worked really hard, but one day, Hermes, God of Thieves, asked them to steal one of Hera's peacocks (he wanted them to be banished from Olympus for stealing because he felt like he wasn't getting enough attention with them around), smart enough to catch on what Hermes was trying to get rid of them (Hermes then had an idea and left to tell Zeus that they had disobeyed him), they said no and went on doing their duties. Soon Zeus heard about the three nymph disobeying Hermes, a god, and banished them to the Camp until they learned how to obey a god(dess) other than their creators.
