Idea from a friend, it's already time for me to make eldritch Female Monsters it seems.

The Queen in Yellow, searching for her King.

You and your trusty catgirl marine biologist first mate go out on a research expedition to the South Pacific to catalogue the strange species down there! What's the worst that could happen?

Indiscriminate science stains the surgeon's hands... along with some other fluids, eheheheheh. Just love that gal.

Lovecraftian entity, a shadow-spawn from beyond the stars, who manifests herself in both a human form and a grotesque natural form. In her human guise, she is a strikingly attractive woman. However, beneath her captivating appearance, hints of her true nature emerge, such as the dark tendrils that curl from her back. In her natural form, she becomes a grotesque embodiment of cosmic horror, with shifting shadows, ethereal mist, and a multitude of writhing tentacles. Despite her eldritch origins, Nycteria displays a profound love and devotion towards her mortal human boyfriend, willing to protect him at any cost.

A clever and seductive traveler with an eye for everything of value... No matter if it's the property of the living or the dead. Gold is gold, hon.
