Wukai are one of the three major species in the world of Wukrii and believed to be one of the oldest species in the world. They are regarded as mostly spirit creatures but can manifest in a variety of ways including a more tactile and physical form if they so choose. This latter ability became increasingly necessary as time went on and other species, including humans, began to evolve and came to populate the world, so as to be able to communicate verbally or in writing with humans without frightening them.
Despite their ancient historical roots, little is known outside of Wukai communities about the secret world of Wukai including their history, culture, or what they are precisely. While it is believed by some that they once lived amongst humans in relative peace, modern recorded history has humans and Wukai living in spaces largely apart from each other, with a fair amount of distrust between the two. The reasons are varied and complex.
Like humans, they appear to have various beliefs and motivations amongst themselves, with some more friendly and others more hostile, and others simply remaining neutral or indifferent. There exists an uneasy and tense peace between themselves and the humans and Demimons, but boundaries are generally respected by most amongst the 3 species. However, border disputes and unwanted incursions are not uncommon from both sides.
Demimon and humans are taught early on to be mindful of treading too far into known Wukai territory. Some report no issues, while others are never seen or heard from again. Adventurers, scholars, the curious, and both the brave and the ignorant often take trips into Wukai territory out of curiosity, in search for knowledge, or for treasure, or to hide from humans or demimons. It is assumed that most untamed and wild parts of Wukrii are thought to be Wukai territory if they are not inhabited by humans or demimon, although this is not always the case.
Wukai are known for having a variety of seemingly magical abilities, often tied to the natural or spirit world. Some can manipulate and summon Wukai familiars, and can take on a variety of forms and perform different functions. They tend to keep to themselves more often than not and prefer to live undisturbed by both demimon and humans. They have a deep affinity for the natural world, and are known for shunning technology, which humans, and some demimon, have embraced. Many humans and some demimons see them as too stuck in their traditions and the past, preventing progress.
Wukai familiars a sub class of wukai. While they are sentient like wukai are, they tend to be simpler creatures often representing manifestations of the natural world in wukai spirit energy form. It is said that once a family of Wukai familiars is bonded to you, they are with you for life, and will even mourn your death before moving on. Generally, only wukai and some demimon are capable of having and utilizing wukai familiars. Much of the details regarding this remains elusive to humans, and the information is guarded amongst the wukai, and even amongst the demimon, traditionally.
