The bits of the Astral sea that accumulated within the Feywild didn't take a spiritual form like that of the Primal Spirits nor created beings to carry out the will of the plane like in the Shadowfell. The energy instead found hosts whom they allow to harness itself. These hosts were the first sentient beings within the feywild, known as the Archfey. These sentient beings then formed five courts that have complete control over the Feywild. Each Archfey has the ability to morph the geography, weather, and fauna of the region they reside in. The Archfey are Godlike avatars able to form pacts with mortal beings. Most Archfey form pacts to spread their influence to different planes or to gain a way to explore other regions as they grow tired of the Feywild. An Archfey cannot cross the Feywild unless a bargain is made that allows him/her to cross the threshold. Some Archfey form pacts out of love too, some do it to gain the upper hand over a rival Archfeys, while others do it just for the fun of it.
If an Archfey is killed the fey creature that kills him/her takes on the mantle as there must always be an archfey that rules over the region. If a non-fey creature deals the death blow then the power spreads among the surrounding Archfey allowing them to lay claim to part of the region that lost an Archfey.
Each court rules and controls regions where their courtiers reside, but not all courtiers live near each other some live further away or in the midsts of courtiers of a rival court. Each region is under the conditions that the resident courtier is associated with.
Each court has a ruler that seems the epitome of what the Court stands for. The lower leveled Archfey are very fickle and change courts according to their whims.
