Goddess Clan

The Goddess Clan is one of the five major races in the world of Nanatsu no Taizai.

Overview
Three thousand years ago, the Goddess Clan waged a great war against the Demon Clan but they are so equal in terms of power and strength which none could defeat each other properly and thus created a balance of power between both races in Britannia.

However, when Meliodas had betrayed his own people for reasons unknown and severely crippled their strength by killing two original members of the Ten Commandments, the Goddesses took this as an opportunity to defeat the Demons with the combined powers of the Giant Clan, Fairy Clan and humans that they allied themselves with. This was the sudden change in the balance of power which has tipped the scales of favor for the Goddess Clan.

As a result, the Demon Clan was ultimately defeated by Goddesses and their allied clans and sealed away in the Coffin of Eternal Darkness for many years until the present day with Hendrickson unleashing the Ten Commandments after incompletely breaking the seal.

Despite their victory against the Demons, the Goddess Clan lost so much of their power and physical forms that they could not remain in the physical world for too long and retreated back to their realm to recover their losses, leaving only the Horn of Cernunnos as its only ritualistic relic to communicate with anyone using it and left a deep religious impact on the people of Britannia.

The only real evidence of their existence is the Druids, a group of humans who worshiped the Goddesses and nature, and despises Demons although Meliodas seemed to be an exception for unknown reasons.

For another unknown reasons, the Goddess Clan still despise Meliodas despite his role that turned his own clan to the brink of defeat by their hand and seemingly aiding them during their battle against the Demon Clan as they ordered Ban of the Seven Deadly Sins to kill him in exchange for resurrecting Elaine back to life by their power via the Horn underneath the underground depths of the Kingdom of Liones.

Appearance
Many of the Goddess Clan are believed and are actually to have angelic appearances with wings that were shown through Elizabeth Liones, when she first activated her powers as the Apostle of the Goddesses. There's even a stone portrait featuring a Goddess triumphing against a fallen Demon.

In combat, they were shown to wear full-plate armor with long battle dress similar to most female Holy Knights depending on their choice of wear.

Physiology
The Goddess Clan appear to be an all-female race. They look like human women, but are much larger than any human and have angelic wings.

Powers and Abilities
The Goddess Clan is an extremely powerful race able to stand on equal ground with the Demon Clan, although it required the cooperation of the fairies, giants, and humans to seal them away. Members of the Goddess Clan share several common abilities:
 * Healing: The Druids who worship the goddesses, channel their power to heal. This healing power has the opposite effect on demons, hurting them and repelling their power.
 * Flight: Given the nature of their wings befitting them of angelic appearances, this presumably allows the Goddesses to fly.
 * Resurrection: Ban sought out the Goddesses to resurrect Elaine, believing that something like that should be easy for them. They do say that resurrection is an easy task, but it has yet to be shown if they were actually being honest.

Trivia

 * The Goddess Clan may be based on the Valkyries from Norse mythology and the Angels from the Bible.
