Some versions of Irish mythology have the Daoine Sidhe eventually divide into two groups: the Seelie Court and the Unseelie Court. Though this separation is more commonly seen in Scottish mythology, Ireland also adopted this division.
The Seelie Court were considered the true aristocrats of the Daoine Sidhe. They were judges, dispensing justice to the other faery when it was required, and served as frequent arbitrators of the many faery quarrels. The Seelie Court was very political, complete with cliques, factions, gossiping, and rivalry.
Sometimes called the ‘Blessed Ones,’ the Seelie were often depicted as a procession of brilliant light riding on the night air. The Seelie Court, as a group, would often use these excursions to find those in need of help. The Seelie were also prone to a great deal of mischief, especially when bored.

They comprise the Slaugh, or The Host, the band of the unsanctified dead who fly above the earth, stealing mortals and take great pleasure in harming humans.
Often called the ‘Unblessed Ones,’ the Unseelie were depicted as a dark cloud riding upon the wind from where their unnerving cackles and howls can be heard. Though not necessarily evil, they were far from kind. These unsavory characters tended towards evil and were often malignant. Some Scottish legends claim that the Unseelie were fallen Seelie, those who could not live up to the strict standards of chivalry of the shining court. They have no method of reproduction, so they enslave mortals whom they think would never be missed and carry them along to become one of them. The Unseelie Court was almost always out to harm, or at least bedevil and trick, humankind.
Some of the members of the Unseelie Court included:
Like many human courts, the Unseelie Court had its own code of conduct, a code which all of the Unseelie had to abide by. The details of this code were:
