Nova

Nova is a fire elemental making her home in a pool of magma within the Caverns. She has full control over the molten rock's temperature and serves as a safe spot in the region, allowing you to take a breather. She also speaks almost entirely in fire and heat puns, for better or for worse.

In-Game Description:
"A woman whose body seems to be made purely of liquified earth and blazing fire, with molten orange colored skin that lazily shifts to darkening shades of red before languidly shifting back to its original orange pigmentation. Her hair is a blazing mane of scarlet that flickers as if made of fire itself, flowing down her back and shoulders and parting on her forehead around her two swept back horns that shift in color from the base up, rapidly transitioning from the orange of her skin to a dark red and ending with pitch black pointed tips."

"Her face is warm and relaxed looking, with blackened, rocky eyebrows positioned above the deep, molten red sclera and bright yellow iris’ of her eyes as they blaze with an energetic light, a nostril-less protrusion of darker orange for a nose, and soft looking obsidian black lips, which open to reveal her gooey molten tongue and mouth whenever she talks or smiles."

"Starting from her shoulders, her arms are covered in solidified black obsidian with small veins of molten orange threading their way all the way down to her clawlike hands that pulse with an inner heat."

"Her voluptuous DD breasts are on full display, occasional dripping small tendrils of lava that trail all the way down her sensual body like sweat, to her shapely hourglass waist and her wide, womanly hips that are covered in various patches of molten red rock, but do nothing to cover her molten orange pussy that drips juices from its exposed yellow slit. The rock covering her hips slowly darkens in color as it goes further and further down her shapely legs until it becomes a deep black, occasionally broken up by warm veins of smoldering orange around her thighs and knees, and below her knees her legs taper down to two jagged points of dark black obsidian, which float off of the ground.",

Event: Lava Hot Spring
While exploring the Caverns, you can come across Nova's magma pool. She will offer you to come and take a dip with her, while also casually saying you are probably gonna have sex with her while you are at it. You can either move on or accept her offer.

While in the pool, you can chat with Nova, relax, get a massage, grope her large tits, bend her over and fuck her, let her ride you or get a titfuck. She is more than happy to provide all of these services, and while you will lose all your Spirit from having sex with her, you will be fully healed after the act, allowing you to continue. Note that messing around in the pool will otherwise keep increasing your Arousal, though you won't lose Spirit from simply relaxing there.
