Willow

Here is my cultsona, Willow! I overdid the watercolor a bit and my camera quality isn't the best, so it's hard to see.

EDIT: I'll be redoing this description so it'll follow the new guidlines and I'll also be posting new art later (probably after May 20th cuz I am super busy now)

Willow guards a door of the cult in the swamp. No one knows what's behind it, but they have been known to open it to unfortunately curious wanderers. Those poor souls are never seen again or are rendered insane. No one knows what they have seen- the meaning of life? The monstrous enormity of the universe? The perfume department? And no one will ever know. They cover their face with a large very realistic moth mask.

Abilities
Willow can use their constantly burning enormous moth wings to fly or spread fire. The candles on their shoulders attract moths and turn them into willow the wisps which lead away and confuse unwanted travelers in the swamp. The willow the wisps can also serve as "eyes" for them to see through.

Weaknesses
Water can't put out their fire, but solving, explaining, or asking them to solve calculus problems will cause their flames to go out. They also cannot go too far from the swamp without bringing extra candles.

Personality
They are quiet but mischevious. They occasionally talk to humans, usually in order to trick them or lead them to their death.
