Leanan Sidhe

Leanan Sidhe is a type of Archenemy, specifically a type of fairy.

Description
A Leanan Sidhe is physically identical to a human female. However, she is normally invisible and intangible to other people. She can designate other people as her lover(s), allowing them to see and touch her. However, only the lover's physical body will be able to touch the Leanan Sidhe; weapons the lover wields will pass through harmlessly. The Leanan Sidhe can give inspiration to her lover but at the cost of draining their life force. The loss of life force results in a physical exhaustion that feels like the lover is carrying a heavy weight. The lover's exhaustion increases if they actively use the inspiration provided to them. There are methods of counteracting this, such consuming a Witch's potion that heals wounds, or forcing the Leanan Sidhe onto another person.
