Athena Series

The Athena series of artificial lifeforms is the life's work of the witch Frostvine. Created through mostly unknown scientific methods involving the sexual fluids of female Angels and Devils, the Athena series was created to be similar to humans, but lack free will, to act as the ideal artificially intelligent servants and toys, which would be sold in order to make Frostvine rich. However, work on the series has been largely experimental, and so far, none of the homunculi in the Athena series have satisfied the design objectives in Frostvine's eyes.

Abilities
Despite being artificial lifeforms, Athena units do have a soul, and so they possess all elements living beings with a soul have as outlined by the Planner Scenario, such as levels, skill levels, and a level cap. But for an unknown reason, unlike ordinary beings, they are unable to level up, so they are permanently stuck at Level 1. Nonetheless, their base fighting ability is much greater than that of the average human, so even at Level 1, Athena units are quite formidable in combat. An inability to grow past Level 1 also means that, unlike other beings with a soul, Athena units won't lose levels over time, and thus retain their combat ability even without training. In addition, some Athena models such as Athena 2.0 have a limited capacity to learn, meaning they can improve their combat ability based on previous data. Artificial intelligence of this level is extremely rare in the Continent, making the Athena series quite notable from a scientific standpoint.

As artificial beings, Athena units can also be created with special functions, such as the ability to change their voice.

Creation and Specifications
The Athena series are artificially created organic lifeforms. They are created using techniques engineered by and known only to the self-proclaimed "great witch" Frostvine, likely with the use of her rare Life Science skill. Besides the sexual fluids of Angels and Devils, the bodies of Athena models are known to be composed of a wide variety of ingredients. Athena 2.0, for example, is known to have been created from many ingredients, including but not limited to: The "life force" of an Athena unit originates from a naturally occurring soul used as an ingredient. The body is created from the mixed ingredients and grown over time, cultivated in strange test tubes. Once an Athena unit's creation is complete, it will undergo metabolic processes and thus require food, sleep, and will also produce waste. However, their artificial body is far more durable than a human's body - Athena 2.0, for instance, once fell from a high tower in Genbu Castle tall enough to kill a person, and suffered little to no damage. It is unknown if the body of an Athena unit ages, or how long their lifespans may be.
