Seven Deadly Sins

"Apparently, the Seven Deadly Sins were the strongest and cruelest order of knights in the kingdom, formed by seven brutal criminals who carved symbols of seven beasts into their bodies. Ten years ago, they were accused of plotting to overthrow the kingdom, and disintegrated after all the Holy Kights launched a general offensive against them."

- Elizabeth to Meliodas and Hawk in The Seven Deadly Sins

were the strongest and cruelest order of knights in the kingdom of Lyonesse which was formed by seven brutal criminals, who had all been convicted for grievous crimes and had carved the symbols of seven beasts onto their bodies. After having been framed for murdering the Great Holy Knight, they were disbanded, and branded as traitors and villains.

Background
This group, which was originally an order of knights serving the kingdom of Lyonesse, became branded as traitors and villains due to being framed for assassinating Zaratras, the Great Holy Knight. It is suspected that one of the members in the Seven Deadly Sins could be a traitor who helped plot the trickery. In addition, one of the Deadly Sins' feats include defeating the troll queen, them having also broken the Great Druid Altar as they did so.

Sins Committed
Each member of the Seven Deadly Sins have committed a grievous crime, for which they were sentenced and judged by the kingdom of Lyonesse, before forming the group.

Meliodas
Meliodas considers his sin to be his failure to protect Danafor, its citizens, and Liz from the kingdom's annihilation. Although the official story is that Melodias lost himself in his wrath and annihilated the Kingdom himself.

Ban
As the only survivor of the Fairy King's Forest, he took the blame of, and was convicted for, destroying the the forest, and killing its guardian saint. As a result, he was sentenced to death, and became known as the Sin of Greed due to his apparent greed for immortality.

King
Since King's sin is sloth, it might be related to his dereliction of his duty as the guardian saint of the Fountain of Youth and the king of the fairies.

Seven Laws of the Seven Deadly Sins
There exist seven laws that each member of the group is required to abide by. So far, only one of these laws was revealed.
 * Law #3: "A Sin shall ask no questions of another member's sin."

Sacred Treasure
Each of the Sins owns a sacred treasure, which were entrusted to them by King Lyonesse when the group was formed, and are compatible with their respective abilities. The weapons are unusable by anyone other than their intended wielder.


 * Meliodas's sacred treasure appears to be a dagger; he sold it to get money for the Boar Hat.
 * Diane's sacred treasure, Gideon, is a war hammer designed for a giant, that is made of a material stronger than steel and weighs approximately 2,200 pounds. It became the reward of Byzel's annual fighting festival after Diane lost it. Diane later regained Gideon during the Holy Knights' attack, quickly forcing them to retreat.
 * Ban's sacred treasure appears to be a rapier. It was stolen during his imprisonment in Baste Dungeon.
 * King's sacred treasure, the Chastiefol, is a spirit spear crafted from a sacred tree only found in the Fairy Realm, is much stronger than steel and possesses the mysterious qualities of the tree, which King's ability, Disaster, draws out. It has several different forms, including a pillow which can act as a shield, different forms of spears, and a large stuffed grizzly bear.
 * Gowther's sacred treasure is not yet revealed, though it may be related somehow to his armor.
 * Merlin's sacred treasure appears to be a crystal ball of some sort.
 * Escanor's sacred treasure appears to be a spear.
