Spoiler Warning: This article contains major spoilers for the entire Lord of the Mysteries novel. Proceed with caution.
Ngetrenz – In the fog-shrouded, steampunk world of Lord of the Mysteries, power is not a gift. It’s a poison. Every potion that grants supernatural abilities is a concoction of cosmic madness, a dangerous substance that must be slowly, carefully, and deliberately digested. To become a Beyonder is to walk a razor’s edge, constantly battling for your sanity, your identity, and your very humanity.
But what happens when that battle is lost? What happens when the potion isn’t digested, when the wrong concoction is consumed, or when an advancement ritual goes catastrophically awry? The results are rarely a simple death. Instead, they are bizarre, horrifying, and often poetically tragic transformations. This is an exploration of the weirdest side effects of drinking the wrong potion—a descent into the true, terrifying cost of power in the world of Lord of the Mysteries.

Why Every Potion Is a Brush with Insanity
To understand the side effects, one must first understand the poison. The power system of Lord of the Mysteries revolves around 22 distinct “Pathways” of divinity, each containing nine advancing levels called “Sequences“. A person becomes a Beyonder by consuming a potion corresponding to a Sequence, typically starting at the lowest rung, Sequence 9.
These potions are not mere magical liquids. Their primary ingredient is a “Beyonder characteristic,” the crystallized essence of a deceased Beyonder or a supernatural creature. Crucially, these characteristics are not inert. They contain the residual will, memories, and madness of their original source. More terrifyingly, they all carry a sliver of the consciousness of the Original Creator, the primordial being from which all Beyonder powers originate—a being whose defining trait is madness.
When a person drinks a potion, they are essentially introducing a hostile, alien consciousness into their mind, spirit, and body. The process of “digesting” the potion is a fight for control: the Beyonder must assert their own humanity and will over the invasive madness of the characteristic. Failure means “losing control,” a state where the characteristic overwhelms the host, turning them into a rampaging monster.
How the “Acting Method” Holds Madness at Bay
For most of history, Beyonders digested their potions through time and sheer willpower, a process that could take years and was fraught with peril. The discovery of the “Acting Method” was a revolution in mysticism, a technique that is arguably the most genius element of the entire power system.
The method is simple in principle but profound in practice: a Beyonder can speed up digestion by consciously “acting” out the core concepts and principles associated with their Sequence’s name. A Sequence 9 “Seer,” for example, acts by performing divinations and respecting the mysteries of fate. A Sequence 7 “Magician” must treat their abilities like a performance, complete with an audience and a dramatic flourish.
This is more than just role-playing. The Acting Method is a psychological discipline. It allows the Beyonder to create a stable mental framework, a persona through which they can safely channel and integrate the potion’s power. It provides a set of rules and principles that help them distinguish their own identity from the encroaching madness of the characteristic. It is the primary defense against losing control, a structured way to impose order on the cosmic chaos they have willingly consumed. Without it, the risk of succumbing to the potion’s bizarre side effects increases exponentially.

The Most Horrifying Potion Mishaps
When the Acting Method fails, or when other factors intervene, the consequences are a testament to the series’ Lovecraftian horror. The side effects are not generic; they are deeply personal and thematically linked to the power being sought.
The Scholar’s Folly: Old Neil and the Whispers of the Hidden Sage
The tragic tale of Old Neil is one of the first and most impactful examples of losing control. A fellow Nighthawk and mentor to Klein, Old Neil was a man haunted by the death of his wife. This grief led him to secretly study forbidden lore in the hopes of resurrecting her. In doing so, he drew the attention of the “Hidden Sage,” a powerful, god-like being from the Demon of Knowledge Pathway.
The side effect Old Neil experienced was not a sudden monstrous transformation. It was a slow, insidious corruption. He began hearing constant, maddening whispers—murmurings that he initially dismissed as a side effect of drinking coffee too late in the day. These whispers were, in fact, the voice of the Hidden Sage, which slowly eroded his sanity and willpower.
Ultimately, he lost control, his mind completely enslaved by the entity he had sought knowledge from. He became a living puppet, a vessel for a cosmic being’s will. This outcome is far weirder and more terrifying than a simple physical mutation; it is the complete annihilation of the self, a side effect of seeking knowledge that man was not meant to know.
The Antigonus Family and Their Maddening Notebook
Sometimes, the “wrong potion” isn’t a potion at all, but a cursed artifact. The Antigonus family notebook, a Sealed Artifact from the Fool Pathway, is a prime example. The notebook contains Beyonder formulas, but it is also an active vector of corruption. It preys on the minds of those who read it, subtly manipulating their perception of reality and driving them toward self-destruction.
The original Klein Moretti and his friends were victims of this artifact. After studying the notebook, they were driven to commit suicide in ways that seemed like “coincidences” or personal despair, their deaths orchestrated by the notebook’s lingering will. The ultimate fate of the Antigonus family‘s patriarch, a being known as the “Half-Fool,” is the final result of this curse. He exists in a state of perpetual madness, sealed away by the Evernight Goddess after losing control and destroying his own kingdom. The side effect here is a curse that infects fate itself, a power that doesn’t just drive you mad but actively arranges reality to ensure your demise.

Zaratul’s Fractured Soul
At the highest levels of power, the side effects of a failed advancement become metaphysical. Zaratul, an ancient and powerful angel of the Seer Pathway, attempted a ritual to advance to Sequence 1, “Attendant of Mysteries.” During this critical ritual, his advancement was disrupted.
The result was not a physical transformation into a monster. Instead, his very soul was ripped into two separate parts. This is one of the strangest fates in the series: not death, not madness in the conventional sense, but a fundamental schism of his being. He was forced to exist as a fractured entity, his power and consciousness divided. This illustrates a key principle: the higher the Sequence, the more abstract and horrifying the potential consequences of failure. The side effect was a direct, conceptual reflection of the power he sought—the power over mystery and secrets, which resulted in his own identity becoming a broken puzzle.
The Unsettling Transformation of the Demoness Pathway
Not all side effects are the result of failure. Some are a planned, yet profoundly bizarre, part of a Pathway’s progression. The Demoness Pathway, also known as the Chaos Primogenitor Pathway, is infamous for this. At Sequence 5, “Banshee,” any male Beyonder who drinks the potion undergoes a permanent and complete gender transformation.
While this is a known and necessary step for those on this Pathway, it remains one of the most uniquely strange “side effects” in the series. It demonstrates that Beyonder powers don’t just grant abilities; they can fundamentally rewrite a person’s biology and physical identity. It’s a stark reminder that the Pathways are not simply skill trees but transformative journeys that demand the sacrifice of one’s original self in more ways than one.
A Compendium of Other Bizarre Side Effects
The novel is filled with other strange and unsettling consequences of meddling with Beyonder powers:
- Murloc Transformation: Low-sequence Beyonders of the Sailor Pathway who lose control have been known to transform into grotesque, fish-like creatures known as Murlocs.
- Memory Loss: Consuming multiple low-sequence potions without fully digesting them can lead to less dramatic but still debilitating side effects, such as the severe memory loss experienced by Captain Dunn Smith.
- Illusory Ravings: A common symptom of impending loss of control across many pathways is the experience of auditory and visual hallucinations, as the barrier between the real world and the spirit world thins for the afflicted Beyonder.
- Insatiable Hunger: Pathways like the Tail-Devourer are built around consumption. A side effect of this power is an all-consuming, insatiable hunger that can drive the Beyonder to devour not just food, but mystical items and even abstract concepts.
Power Always Demands a Price
In the world of Lord of the Mysteries, the weirdest side effects of drinking the wrong potion are never random. They are terrifying, poetic consequences that reflect the nature of the power being sought. A seeker of knowledge is enslaved by whispers. A family that toys with fate is unraveled by it. An angel of mystery has his soul fractured.
This is the core horror and the narrative genius of the series. Power is a transaction, and the price is often a piece of your humanity, your identity, or your sanity. Every sip from a Beyonder potion is a gamble, a bet that you can master the madness before it masters you. And as these bizarre tales show, losing that bet leads to a fate far stranger, and far worse, than mere death.
