Navigating the dark and twisted streets of Krat in Lies of P introduces players to many unfortunate victims of Ergo experimentation. Among these tragic figures is Test Subject 826, a unique human survivor who eventually transitions into a valuable merchant. Finding this hidden character and completing his storyline requires careful exploration during the game's final chapters.

Finding the Initial Location in Arche Abbey

To begin this questline, you must progress deep into Chapter 11 until you reach the vast structure known as Arche Abbey. Navigate through the area until you reach the Arche Abbey Outer Wall Stargazer. From there, you need to explore the lower structural levels and locate a large vertical room featuring an extensive elevator shortcut.

Test Subject 826 is waiting at the bottom of a long ladder near a secure corridor that links back to the main path. Interacting with him here will reveal his fragmented memories and establish his desire to escape the collapsing abbey. Speaking to him completely is a mandatory milestone before his location can shift later in the narrative.

Relocating to Rosa Isabelle Street

Your next meeting with the survivor cannot occur until a major boss fight is concluded nearby. You must successfully defeat Laxasia the Complete, who serves as the ultimate gatekeeper of the upper abbey areas. Once this formidable boss has been cleared, Test Subject 826 will officially pack up his minimal belongings and journey to the city center.

To locate his new position, teleport over to the Rosa Isabelle Street Entrance Stargazer and head toward the bridge overlooking the burning city streets. You can track his proximity by listening for an unusual humming sound drifting down from the stone overpass. He settles securely on this bridge, transitioning from a helpless victim into an active merchant for the remainder of your playthrough.

Unlocking the Quest Rewards and Merchant Stock

Meeting Test Subject 826 on the bridge allows you to purchase several high-tier items that are entirely exclusive to his storefront. His stock features essential defensive upgrades, specialized weapon elements, and rare decorative attire for Pinocchio. Speaking to him in this final location also triggers the unlock for the Happy gesture to complete your collection.

Completing his dialogue lines provides deeper narrative insight into the dark experiments carried out by the Alchemists. Players looking to optimize their characters will find his stock vital for preparing their final endgame builds. Ensuring his safety and tracking his movements offers a satisfying conclusion to one of Krat's most mysterious side stories.
