The Moon King and the Sisters

High in the heavens there rules a figure more powerful and perfect than any mortal could comprehend. The Moon King, Raiden; an immortal, a god. His is a most cold and haughty appearance, his primary form being that of an old man with cheekbones as high on his face as his abode is in the sky, and eyes narrowed and frigid, both milky pale.

The Moon King's daughters, the twins Karasu and Washi, are no less unnerving. Both identical in appearance save for their weapons, they are garbed in dark cloaks, wear broad-brimmed peasant hats, and over the face of each is an eerily smiling Noh mask. They are rarely seen apart, and serve with sadistic pleasure as the Moon King's assassins.

Both the Moon King and the Sisters trive in the shadows, many of their abilities only being active while hidden from the light. They live in a distant realm, and are loath to interact with mortals. Only those who the Moon King believes to be of use does he tholerate, granting them slivers of his power in exchange for their services.

Twin Terrors. The Sisters each have the same statblock, with the variations detailed below. The Moon King, being a god, is beyond stat blocks, but is presumed to wield tremendous power. The Moon King can be a patron to warlocks serving an archfey.

Variant: Karasu

Karasu wields a chain-scythe, a devastating weapon that allows her to strike from afar, bind foes, and drag them to her. She gains the following action option.

Chain-Scythe. Melee Weapon Attack: +10 to hit, reach 20 ft., one target. Hit: 15 (2d8 + 6) slashing damage plus 18 (4d8) necrotic damage. If the target is Large or smaller, Karasu can force it to make a DC 15 Dexterity saving throw or be restrained. As a bonus action, Karasu can release the restrained target or pull it up to 15 feet closer to her.

A target restrained by the chain can use an action to make a DC 15 Strength or Dexterity check (target's choice). On a success, the creature is no longer restrained by the chain. On a failure, the creature takes 7 (2d6) slashing damage. Karasu can have only one creature restrained in this fashion at a time, and must remain within 20 feet of that restrained creature, but can continue to attack with the scythe on the other end of the chain.

Variant: Washi

Washi wields a full-length katana and carries with her a wand of binding. When Washi casts hold person while wielding this wand, she can target up to three creatures. She also gains the following action.

Katana. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 17 (2d10 + 6) slashing damage plus 18 (4d8) necrotic damage.
