Quillestials are created rarely when Moodhogs die. In order to be created, the Moodhog would have had to absorb a large quantity of emotional energy during its life, and, had to have died within close proximity to beings aligned with the good aligned spectrum that it had familiarity with. A quillestial takes the form of an adolescent human whose eyes change color to reflect their mood. It also has a pair of wings that, when not in use, simply phase out into the ethereal plain. Characters with the ability to do so can see the quillestial wings even when they are not materialized. Quillestial attitudes can vary but usually consist of child-like demeanour, favoring harmless activities such as games, or pranks of varying degrees. They are, however, very susceptible to mood swings, and as such can be unpredictable. Despite their appearances, they are able to become very serious when the need arises, and due to their immortal nature, can potentially be thousands, millions or more so old.
Quillestials as stated are rare beings, but those that do exist are very commonly found on the material plane. Quillestials commonly seek out people who have negative emotions, such as pain, sorrow, fear and such. They do this because a quillestial dislikes these emotions, so by seeking them out, they can try to remedy whatever is causing them. It is not unusual for a quillestial to locate a humanoid showing these signs of emotional distress, and spend several years, if not more to help the individual. The easiest way to procure a favor from a quillestial would be to challenge it, and defeat it at a game of its choice, but be wary for these beings could have spent thousands of years or more playing said game, and defeating them certainly won't be easy.
