Galand

is a demon who is a member of the Ten Commandments, a group of elite warriors of the Demon Clan handpicked by the Demon King himself. He was sealed away along with the rest of the clan in the Coffin of Eternal Darkness until he was set free by Hendrickson.

Personality
Galan has been shown to be very sadistic and battle crazed, as he was very eager to go to battle against new enemies despite most of his magical powers being drained and was joyful to still find powerful people after centuries of being sealed.

3,000 years ago
Along with the rest of the Demon Clan, Galan was sealed away by the Goddess Clan after losing the Ancient War against the Four Races (Human, Fairy, Giant and Goddess Clans).

Current arc
After Hendrickson manages to weaken the seal on the Coffin of Eternal Darkness, Galan and the rest of his fellow Demon Clan members appear before Fraudrin (in Dreyfus' body) and the terrified ex Great Holy Knight. Shortly after being updated on the current state of Britannia, Zeldris suggests that they head East for Edinburgh Castle to recuperate their severely drained magical powers. In agreement the Ten Commandments depart Zhuhur Valley, leaving Hendrickson alone.

Arriving at Edinburgh Castle, Galan and his fellow Ten Commandments find it in ruins, concluding that it was Meliodas who caused the destruction of the castle as if there was a great battle fought there.

Abilities/Equipment
Like all members of the Demon Clan, Galan possess a Black Mark similar to Meliodas. He is capable of utilizing his black mark to form wings for flight. As a member of the Ten Commandments, he may be deemed exceptionally powerful. His aura, along with the other Ten Commandments, was immense enough to have Hendrickson break into a sweat of fear. His power level has been measured at 26,000 in his depleted state, a magnitude greater than any of the Seven Deadly Sins revealed thus far.
