The Elder Gods

The Elder Gods are a group of immortals who are believed to have created the Nameless Kingdom.

The Universe
The embodiment of the Universe is female and prefers to be called Lucy/Lucie. She created this reality but rarely intervenes in the course of events.

The Primordial Trinity
The Primordial Trinity are a group of three incredibly powerful gods, who are all almost as old as the Universe herself. They are more deceitful and manipulative than their peers, and often act in a childish and immature fashion in spite of their age. They are :

Life
Death's counterpart and the Goddess of Life. She does not appear in the series.

Mrs. D (Death)
Life's counterpart and the Goddess of Death.

Timothée (Time)
The most powerful of all of the Elder Gods (save perhaps the Universe herself) and the (genderfluid) God of Time.

Others
There are an unknown number of other gods and goddesses, who each seem to embody a principal, element or structure.
