Unseelie Court

The court of the Autumn and the Winter of a swath of different Fae species that are of the insectoid appearance. They hail in the new seasons of Autumn and Winter by causing the Harvest to bloom and legends have it, it's them who paint the leaves red, orange, and yellow. They also bring in the first cold winds of the year and with it, death.

A Debt With Death
The Unseelie's long lifespans are a blessing from the Old God Tartarus in return for their duties. The Unseelie fae annually take souls of those who passed over the year as offering to Tartarus. They then receive the Seeds of Spring from the Old God, and deliver those to the Seelie Court to plant for the next seasons.
