Angel (Cavender Is Coming)

Angels are a humanoid species from Heaven, many of whom are tasked in guarding select Humans.

Biology
Angels are externally identical to Humans, but possess vast essokinetic abilities, allowing them to perform various miraculous feats such as rewriting time, altering memories, teleporting themselves and others across space and dimensions, summoning objects, and writing in the air with energy. Their abilities rely on their concentration, so inexperienced angels may accidentally create the wrong thing or fail to summon a piece of something, and their reality-altering powers seem to activate only upon a hand gesture involving licking their thumb and then stamping said thumb into the open palm of their other hand. Despite their incredible power, angels appear to visibly age, and are susceptible to the effects of alcohol and other drugs.

Culture and society
Angels are organized into at least three castes, which include apprentice angels, guardian angels, and an executive branch of angels, although it is known that there are other classifications for angels. Angel apprentices train to become guardian angels, eventually undergoing a test where they must improve the life of a select Human within 24 hours. If they succeed, they will earn their 'wings,' which are a sort of medal of distinction, taking the form of decorative wing-shaped ornaments worn on their shoulders. Angels strongly value ideal standards of 'angelic' behavior, especially for apprentices and guardians, which involves abstaining from indulging in any earthly vices or slacking off on the job. Angel apprentices who fail their tests are 'reclassified' to an unknown lower rank, which is quite feared by apprentices. Angelic classification is handled by at least three divisions of a department known as Celestial Division Angel Placement.

While angels usually change their wardrobe to fit wherever they end up, angelic clothing worn in heaven usually consists of white robes and boots. The angelic language is identical to English, and angelic establishments are known to have no walls, simply appearing to be islands suspended in space, although they also possess free-standing doors, which appear to serve as either portals or a sort of teleportation beacon.

History
Angels have served as guardians to select Humans for an unknown period of time. By the mid-20th century, a considerably incompetent angel apprentice, Harmon Cavender, routinely failed his guardian angel test, and got addicted to Earth's liquor and cigars. Due to this, the office of the 3rd Celestial Division Angel Placement called him in, where the angel chief berated Cavender for his failures, but gave him one last chance to prove himself before reclassifying him. Cavender was assigned to a clumsy Human woman named Agnes Grep, offering to give Cavender his wings if he could improve her life in 24 hours.
