Fey
As it is written in the Foundation of Ah'Resh:
"The fey creatures were a by-product of the magic used by the Ah'Mahnim to create the Bah’Er. They are thought of by most humans as the product of myth and legend, but they are real and live in the Wilds. This magic resides inside all Fey, making them magical creatures. Many of these creatures, the Bah’Er befriended and sought out, giving them names and a purpose. In Ah'Resh fey creatures include all of the fey in D&D 5E.
