Calypso's servants tend to her everyday needs. They are somewhat clumsy, as when they once opened a can of Pepsi for Hephaestus, and it sprayed all over him, making Hephaestus comment about Calypso needing automatons instead.
The servants are seen in Calypso's cave doing chores for their mistress, such as folding towels and washing spoons. Leo Valdez, after landing on Ogygia, remarks that the scene reminds him of the invisible aurae from Camp Jupiter.
After a few days being trapped on the island, a pitying Calypso sends her servants to leave Leo stew and cider, as well as new sets of clothes after he burnt his old ones. She eventually sent a pair of magic clothes that will not burn, expand, and stay clean.
After being restored to life by the physician's cure, Leo returns to Ogygia with Festus. Calypso's servants leave two suitcases at their mistress' feet, before she flies off with Leo and Festus from Ogygia.
- These servants are very similar to the invisible voices that served Psyche in Eros' palace in mythology.
