Shenxian

Call them Fae, Faerie, Youkai, Yogoe, Xianzi... They exist in myths in the Old World, but here in Tianxiajie, they are very real.
They exist in an Otherworld (Shenhuajie), which, when the volcano Wotutubo Shan blew its stack in 2 KPC, opened a fissure between the Otherworld and Tianxiajie.
Shenxian are not a single species, but are rather more like a taxonomic "Family" for a myriad of species, all of which come from Shenhuajie (unlike the Mythomorpha, which are all native to Tianxiajie, though they were altered/created by Moliliexia - The Rift).
