Nyx is the owner of Mutatio, a potion shop hidden in Paradise Mall. She presents herself as a witchy figure with an English accent, but the occult trappings are largely a façade. Her true expertise lies in advanced genetic manipulation and the control of “essence,” which she describes as the fundamental catalyst for transformation.

Raised in Blackthorn Manor, Yorkshire, by a geneticist mother and an archaeologist father, Nyx was exposed early to both scientific theory and obscure traditions. Her work drew controversy in the UK, forcing her to flee to Summer City — a place where extreme experimentation is more anodyne.

Nyx treats the human body as a flexible system to be redesigned at will. Her views on identity and transformation are pragmatic, though she often frames them in philosophical or historical terms.

Gameplay Role

Nyx’s services revolve around essence — a distillation of the player’s core Intellect, Fitness, and Charm stats that can be extracted, traded, and repurposed. She offers unique and often irreversible alterations, making her shop a destination for players seeking to maximize their potential.

To begin, you’ll need to trade some of your stats for essence. Nyx makes it clear though, that her extraction techniques are most effective on males. Meanwhile, her application techniques for essence are more effective on females. For that reason, it’s wise to sell stats to Mutatio as a male and purchase stats as a female.

• Stat Exchange – Trade away points from one stat (Intellect, Charm, Fitness) )in exchange for essence, or purchase new stat points using essence and additional cash. This is her main source of profit, and the introduction to all functions at Mutatio.
• Side Effect Management – Permanently remove unwanted side effects, or restore previously removed ones at minimal cost. The longer you deal with a side effect, the more essence it costs to remove.
• Stat Maximum Upgrades – Increase the player’s maximum allowable stat values, bypassing the usual permanent caps. These upgrades have a steep cost in both essence and cash.
• Phallus Size Adjustment – Increase or decrease size as part of a stat exchange service. A random buff to your dick’s Length, Girth, and Ballsize will be applied with each purchase. Every subsequent upgrade grows more expensive.
• Transformation Extension – Extend the duration of an ongoing X-Change gender transformation by 24 hours.
• Transformation Termination – End an active X-Change transformation early, unless blocked by special conditions such as pregnancy. Not all pills can be ended early, such as a Cum-Cure.
