Arriving at Rivington in Act 3 of Baldur's Gate 3 instantly exposes adventurers to a dark conspiracy rippling through the local community. The tragic demise of Father Lorgan at the Open Hand Temple sets off a complex whodunit scenario that demands acute deductive reasoning. Solving this intricate case completely reshapes your understanding of the broader political machinations taking place within the Outer City limits.

Initiating the Investigation at the Temple

To officially begin your search, players must head inside the main chapel building located near the entrance of Rivington. Sister Yannis will outline the official narrative, which falsely blames a local refugee for the gruesome crime. Speaking directly to the dead priest using specialized necromancy spells yields valuable hints regarding the true identity of the assassin.

After gathering baseline testimonies from the panicked temple staff, exploring the actual crime scene becomes the primary objective. Inspect the direct vicinity of the chapel altar to note specific physical details surrounding the holy man's final moments. These early steps confirm that an unnatural force is operating secretly within the sacred grounds.

Exploring the Subterranean Vaults

Progressing the narrative requires adventurers to locate the secret hatch situated inside the temple kitchen area. This opening leads players directly down into a damp storage cellar filled with hidden buttons and ancient brick walls. Interacting with the conspicuous buttons placed behind the hanging heraldic signs reveals a heavy stone door.

Bypassing this secret portal allows your party to cross into a expansive network of natural cavern structures. Be fully prepared for an immediate combat encounter against aggressive shape-changing monsters lurking within the shadows. Defeating these hostile entities provides access to crucial physical clues that link the murder to a sinister organization.

Discovering the Murder Weapon and Flowery Key

Once the combat encounter settles, search the bodies of the fallen adversaries to recover a unique ornate key. Nearby, players must pass a passive perception check to uncover a discarded dagger hidden amidst the rocks. This specific weapon represents the missing piece of physical evidence required to break the official investigation wide open.

The retrieved flowery key corresponds to a highly restricted section located further north within the city borders. Adventurers should carry these specialized items safely out of the caverns to confront the corrupt local authorities. Presenting these items to Investigator Valeria at the nearby tavern effectively updates the overarching quest parameters.

Tracking the Culprit to Fraygo's Flophouse

The final phase of the investigation directs your companions directly toward a crowded local boarding house. Use the previously discovered key to gain entry into the topmost room accessible through a hidden wardrobe door. Inside this secret chamber, players will uncover a detailed hit list containing the names of prominent local citizens.

Reading the incriminating logs completely validates your suspicions regarding the grander conspiracy active in Baldur's Gate. This discovery grants players official clearance to enter the lower city gates with a clean reputation. Successfully navigating this questline ensures your group remains ahead of the hidden cultists plotting in the dark.
