The Coven Of The Night Sky
The The Coven Of The Night Sky, headed by the arch-witch Astrea Avarielle, is an organization of witches under her patronage based in [Billeth Vel].
Their primary goals are to spread knowledge of magic, protect the moon lizards, create magical solutions to the people's problems, and occasionally help rebuild the city.
The organization is known by name to most in the city, but most don't exactly know what they're doing. Astrea herself is a frequent enough presence in the city that many people have a story about encountering her, or at least what seems to be her. Her followers do the majority of work around the city though, albeit not nearly as much while they're in study. (Level 1-3 witches rarely venture from Gelūs Salvōrae itself)
She offers tutelage to any she finds that are naturally gifted in magic, and whom she deems to not be 'a total piece of shit' in an effort to spread the knowledge of magic, and thus the things it can create and solutions it offers, to as many as possible.
While out on seemingly random walks, Astrea will often assist people with any variety of problems they might be having via roundabout, convoluted, inane, or particularly odd magical means. A citizen might complain of their walk to work being too long, or too difficult to navigate, and then be offered an oddly restricted ring of teleportation, or temporary wings, or spider legs. Someone lacking a functioning staircase might have a levitation field installed in their house, or a pad of gel that they can bounce up from and take no damage when they fall on. If she's feeling particularly adventurous, they might get a demiplane filled with gates to different floors or locations.
Moon lizards that she encounters are typically enchanted with some form of protective magic, or healed of any injuries or restraints, or occasionally given minor magic items.
The most likely thing people will know them for, though, is the odd variety of unnatural herbs and plants whose spores and seeds seem to make their way out of the Gelūs. These plants tend to have -naturally or with relatively little processing- the same effects as some medicines, minor potions, mostly-harmless drugs, or other miscellaneous alchemical concoctions.
