Diplomatic action
The Archfey find the first tribes of humanity and rise them in the image of the Archfey.
When the the Archfey first met humanity they were intrigued at such strange creature. While they were primitive like the animals they hunted; the humans were intelligent enough to use tools and develop communities. In turn humans worshiped the Archfey like Gods which the Archfey enjoyed thoroughly. Raising humanity from its barbarism the Archfey began to coexist with humanity. It was the first cross breeds between man and Archfey that created the Sidhe. The Archfey found that humans were enjoyable to court and lie with and managed to die long before relationships became difficult for the Archfey.
