The Seelie Court, also known as the Summer Court, is a massive group of fairies and fey that is associated with the season of Summer, the growth of Life, and the comfort of fire. They tend to be more subtle then those of the Unseelie Court, and more emotional as well.
The Seelie Court is made up of Kings, Queens, Ladies, Knights, and some lesser positions. The exact number of any position is unknown at this time, though some guesses can be made. (ie There is only likely one King and one Queen). Those Fae associated with the Court of Summer tend to have coloration that corresponds to the colors of the summer season. (ie scarlet hair, gold eyes, tan skin).
The Seelie court were known to seek help from humans, to warn those who had accidentally offended them, and to return human kindness with favors 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 Throne' and 'The Golden Ones' and 'The Light Court'. Seelie Court faeries are seen as generally "good", mainly because they are less evil and possess a more lighthearted attitude than their Unseelie counterparts.
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. Even though Seelie Court faeries expect courtesy and favors to be fulfilled, otherwise, they demand retribution and avenge what they see as insult or offense.
The agents of Summer are associated with the season, and share powers in line with it. Many can promote and control plant growth, wield fire with ease, and heal living beings. All Seelie fae are stronger during the day then at night as well as during the Summer, and Unseelie's Ice magics are extremely dangerous to them.
