The Endless are a family of the embodiments of powerful natural forces. From oldest to youngest: Destiny, Death, Dream, Destruction, Despair, Desire, and Delirium, who was previously known as Delight.
- Destiny, the oldest, also seems to be the tallest to mortal eyes. He wears a cowl over his eyes. He is blind, but can still see. Destiny’s sigil is the book that is chained to his wrist.
- Death appears to be an attractive goth girl. She is the sibling closest to Dream and he frequently relies on her for advice and help. Her sigil is the ankh that she wears around her neck.
- Dream is the moody, pale, and dark-haired protagonist of the series. His 70-year imprisonment changed his personality, the effects of which are shown throughout the series. His eyes glitter strangely, like twin stars. His sigil is the helm that he wears into battle.
- Destruction is a broad-shouldered, red-headed man. He abandoned his realm 300 years ago. Since then, he has made very little contact with his siblings. While he was with the family, however, he was boisterous and warm-hearted. His sigil was a sword.
- Despair and Desire are twins. Despair appears to be a squat, morbidly obese woman. She wears a ring with a hook on her finger and uses it to cut her flesh. That ring is her sigil. Desire is a man or a woman or both or neither, depending on what you want. His/her sigil is a glass heart.
- Delirium, the youngest, used to be Delight. No one knows why she changed, except for herself. Her hair changes on whim, ranging from long to shaved, from red to orange to multicolored. One of her eyes is blue with flecks of silver and the other is emerald green. She appears to be around 14 years of age, and the other Endless are often protective of her. Her sigil is a swirl of colors.
