Fairies

Fairies are classified in a variety of ways -the division into the Seelie Court and the Unseelie Court.

The categorization of fairies based on court is whether or not they are a light or dark fairy. Light fairies are known for playing pranks on humans and having a light hearted attitude, forgetting their sorrows quickly and not realizing how they might be affecting the humans they are playing pranks on.

Seelie Court

The Seelie court are known to possibly seek help from humans, to warn those who had accidentally offended them, and to return human kindness with favours of their own. Still, a fairy belonging to this court will avenge insults and could be prone to mischief.

The most common time of day to see them is twilight. Other names for the Seelie court are 'The Shining Throng' and 'The Golden ones' and 'The light Court'.

Unseelie Court

The Unseelie Court consists of the darkly-inclined fairies. Unlike the Seelie Court, no offense is necessary to bring down their assaults.
As a group (or "host"), they appear at night and assault travellers, often carrying them through the air, beating them, and forcing them to commit such acts as shooting elfshot at cattle.
Like the beings of the Seelie Court who are not always benevolent, neither are the fairies of the Unseelie Court always malevolent. Most Unseelies can become fond of a particular human if they are viewed as respectful, and would chose to make them something of a pet.
