Wispit are actually two, almost inseparable symbiotic lifeforms. One is a docile, cloudlike mass, while the other is a small, winged humanoid (height clocking in at 2 to 3 ft). When necessary, wispit refers to the humanoid, while wispit cloud is, well, the cloud. In addition, wispit have no legs, but a sort of tail that helps them nestle into the cloud. Their hair tends to be long, and their ears are more like horns, being long, spiked, and sturdy.
The two species are totally defined by their symbiosis. For example, wispit are intellectually precocious compared to other sapient species. The cloud protects the young wispit and allows it to develop its mental faculties faster than its physical ones. While the cloud allows both to fly (their main mode of movement), the wispit’s wings make for much quicker movement. And, naturally, a wispit is strongly incentivized to nurture, feed, and protect their cloud.
Wispits and their clouds are born and raised together and have nearly identical lifespans. A wispit that loses its cloud is crippled, while a cloud without its wispit becomes ill and will often stop eating. Much like a body will reject an organ transplant if it does not recognize the organ’s cells, a wispit and clouds’ bodies will reject attempts to be separated or have the other replaced.
Since gasses can’t naturally retain their shape, carry weight, or anything like that, wispit clouds need a touch of magic to live. Consequently, there are no wispit in nonmagical rings.
