Discover the Truth about the AbsoluteSpoilers

Discover the Truth about the Absolute follows the investigation into the mysterious power guiding the Cult of the Absolute and the True Souls who serve it.

The Absolute is presented throughout much of Baldur's Gate 3 as the central power of a growing religious and military movement. Its followers treat it as a deity, while its clerics and acolytes use that belief to recruit, command, and organize the Cult of the Absolute. The investigation begins with that public image, but the cult's actions make the nature of its supposed god increasingly difficult to reconcile with an ordinary faith.

The Absolute's influence is closely tied to illithid tadpoles implanted in selected hosts. These psionic parasites can grant their hosts unusual abilities while also connecting them to the wider network of control surrounding the cult. In this structure, True Souls function as elite agents: they are infected individuals who use the Absolute's authority to direct other followers and advance the cult's campaign across the region.

The central revelation is that the Absolute is not a goddess. It is an enslaved Elder Brain, later revealed to be a Netherbrain, and it is being used in a plan to dominate Faerûn. Ketheric Thorm is one of the key figures connected with the cult's operations at Moonrise Towers. The player characters can investigate this conspiracy because a mysterious artifact protects them from the Absolute's mental control, allowing them to question the cult's claims rather than simply submitting to them.

WalkthroughSpoilers

01
Establish the central question of the investigation
Treat the Absolute as a claim to investigate
When the Cult of the Absolute describes its power as a goddess, record that as the cult's belief rather than accepting it as the answer. Compare the language used by followers with the cult's coordinated behavior and the unusual abilities of its important agents.
Location: Early encounters with the Cult of the Absolute
TipDo not confuse religious titles used by the cult with confirmed information about the entity behind them.
02
Connect the Absolute to illithid parasites
Trace the source of the cult's influence
Investigate the illithid tadpoles carried by members of the cult and by the player characters. Their psionic connection explains why the Absolute can influence people across ordinary social and military boundaries, while the special abilities they provide help the cult identify and elevate selected hosts.
Location: The wider investigation into the tadpoles
Watch outThe presence of a tadpole does not by itself prove that every infected person shares the same goals; distinguish the parasite from the host's choices.
03
Map the cult's chain of influence
Identify the True Souls
Separate ordinary followers from the infected elite agents called True Souls. These figures use their connection to the Absolute to act as representatives and commanders, so learning who they are clarifies how the cult turns a mysterious power into practical authority.
Location: Cult-controlled communities and operations
TipPay attention to titles and behavior: True Souls are important because they combine the cult's social authority with the abilities associated with the tadpoles.
04
Find the cult's operational center
Follow the cult toward Moonrise Towers
Use the cult's organization and its named leadership to direct the investigation toward Moonrise Towers. The location is associated with Ketheric Thorm and serves as a concrete place to examine the movement's operations rather than relying only on rumors about the Absolute.
Location: Moonrise Towers
Watch outThe investigation reaches major plot revelations around the cult's leadership, so make a separate save before entering story-critical areas if you want to explore alternate choices.
05
Understand why resistance is possible
Account for the mysterious artifact
Notice that the player characters can resist the mental control that affects or empowers the cult's followers. The mysterious artifact is the established explanation for that protection, making it possible to question the Absolute and continue acting against the cult instead of becoming one of its unquestioning agents.
Location: The player characters' encounters with the Absolute's influence
TipThe artifact is not merely a background mystery: its protection is what allows the party's investigation to remain independent.
06
Identify a key figure in the cult's operations
Connect Ketheric Thorm to the conspiracy
Treat Ketheric Thorm's association with Moonrise Towers as part of the larger structure behind the Absolute. His role helps show that the cult is not only a religious alliance but also an organized operation with powerful figures directing its campaign.
Location: Moonrise Towers
Watch outThis step leads into major story material involving the nature of the Absolute and should be considered spoiler-heavy.
07
Discover the Absolute's true nature
Reject the false identity of the Absolute
The investigation ultimately reveals that the Absolute is not a goddess. It is an enslaved Elder Brain, later revealed as a Netherbrain, whose power is being used in a plan to dominate Faerûn.
Location: The later revelations of the main story
Checkpoint
08
Understand the political and religious machinery around the Absolute
Reframe the cult's symbols and hierarchy
Once the truth is known, reinterpret the cult's religious presentation as a recruitment and control structure rather than proof of divine status. The Absolute's symbol combines imagery associated with the Dead Three, reinforcing the alliance and ideology used to support the cult's public identity.
Location: The cult's wider story and iconography
TipThe symbol is evidence of the cult's alliance and presentation, not evidence that the Absolute itself is one of the Dead Three.

Mission mechanicsSpoilers

This investigation is driven less by a single quest marker than by the accumulation of evidence. The player encounters a movement that presents the Absolute as a deity, then learns that its authority is reinforced through psionic links, infected agents, and a coordinated network of followers. The narrative mechanics therefore reward examining who is speaking for the cult and how those people gained their position.

The tadpoles perform two connected story functions. They grant hosts special abilities, which helps explain the status of True Souls, and they provide the illithid connection through which the Absolute exerts influence. The existence of the mysterious artifact creates the opposing side of that mechanic: the player characters can remain aware of the manipulation and investigate the system from outside it.

Moonrise Towers functions as an important point of convergence for the investigation because it links the cult's abstract religious message to a named leader and a physical center of operations. The final revelation changes the framing of every earlier clue: the apparent goddess is an enslaved Elder Brain later identified as a Netherbrain, and the cult's activity is part of a plan to dominate Faerûn.

What works and what does not

Strengths

The investigation ties the game's central mystery to recurring characters, factions, locations, and gameplay systems rather than isolating it in one exposition scene.
The contrast between the cult's religious language and the tadpoles' psionic function gives the player multiple ways to interpret the same threat.
The artifact's protective role preserves player agency by explaining why the party can challenge the Absolute's influence.
The mystery escalates from a suspicious cult to a region-wide domination plan without requiring the player to accept the cult's theology.

Weaknesses

The investigation is distributed across the main story, so its exact order can vary and a player may encounter clues before understanding their significance.
The source pack does not establish a single fixed route, encounter count, or complete list of rewards for this quest.
The Absolute's identity is a major spoiler, so reference material about the quest can reveal the central twist even when discussing its early stages.

Best uses

Use this quest as a story reference when connecting the Cult of the Absolute, True Souls, Moonrise Towers, and the larger illithid conspiracy.
Use the artifact and tadpole details to distinguish resistance to the Absolute from ordinary opposition to the cult.

Choices and consequencesSpoilers

Accept the Cult of the Absolute's claims without investigating them
The player may follow the cult's framing of the Absolute as a deity, but this approach obscures the connection between the cult, the tadpoles, and the illithid power behind it.
Use the party's protection from the Absolute to question the cult's influence
The player can continue investigating the cult as an outside observer and pursue evidence about the True Souls and the Absolute's true nature.
Approach the cult through its leadership and Moonrise Towers
The investigation reaches major revelations about the cult's operations and Ketheric Thorm's association with them.
Spoiler
Treat the Absolute's symbol as proof of direct divine identity
This interpretation is misleading; the symbol reflects imagery associated with the Dead Three and the alliance supporting the cult's public identity.

Failure conditions

Accepting the cult's explanation as the complete truthThis does not necessarily end the quest, but it can leave the player without the context needed to understand the tadpoles, True Souls, and the wider conspiracy.
Losing track of the investigation's named termsThe Absolute, True Souls, Cult of the Absolute, Moonrise Towers, and Ketheric Thorm describe connected parts of the mystery; confusing them makes later revelations harder to follow.
Entering major story areas without preparing for spoilersThe investigation's later stages contain the central identity reveal and should be approached with the expectation that they disclose major plot information.
