Being bound by matrimony to a dark fey has done this cultist well. No matter their true age, they remain flush and lush at the peak of youth. That is of course, if one can get past their pure-black eyes and the small, curling horns peeking from their temples. Exposure to the waning court marks the waning spouse in other ways, their skin is too pale, their fingers too long. Many wear revealing clothing, showing the branding and scars given to them by their lovers as well as other trinkets fashioned from amber and gold. The spouse carries a special sickle, fashioned from their fey’s last lover. Not only does this couple with the cultist’s strange powers, but it reminds them of the consequences of being boring.

Serial Monogomy. Say what you want about the waning court, but these dark fey are lawful creatures. When they find a mortal they wish to take as a lover, the autumn fey seals the deal and never strays. In turn, the waning spouse is saturated with fell energies by the marriage contract, ceases to age, and finds their psyche awakened. The waning fey treats their spouse as a trophy at best, however, showing them with equal parts abuse and adoration. The dark fey expects loyalty in return and if the mortal takes another lover, they are made an example of. Occasionally, a waning noble tires of their spouse but these poor souls are disposed of quietly. Either way, the fey is soon back on the market.

Telekinetic Thrust.

The waning spouse targets a creature or unattended object within 30 feet of it. A creature must be Medium or smaller to be affected by this magic, and an object can weigh up to 150 pounds.

If the target is a creature, the waning spouse makes a Charisma check contested by the target's Strength check. If the poltergeist wins the contest, the waning spouse hurls the target up to 30 feet in any direction, including upward. If the target then comes into contact with a hard surface or heavy object, the target takes 1d6 damage per 10 feet moved.

If the target is an object that isn't being worn or carried, the waning spouse hurls it up to 30 feet in any direction. The waning spouse can use the object as a ranged weapon, attacking one creature along the object's path (+6 to hit) and dealing 5 (2d4) bludgeoning damage on a hit.
