When exploring the treacherous halls of St. Frangelico Cathedral Library, players encounter a distressed woman named Cecile who presents a crucial side quest. She urgently requests assistance in recovering a significant religious artifact known as the Archbishop’s Holy Mark. Successfully completing this mission yields substantial gameplay advantages that significantly enhance your progression through this challenging area.

The Archbishop’s Holy Mark can be found in his quarters.
After committing to locate the sacred artifact, your journey begins at the St. Frangelico Cathedral Library Stargazer. Proceed through the doorway positioned to the left of the water feature, advancing carefully down the adjacent corridor. The initial chamber contains several hostile entities that must be neutralized before safe passage can be achieved.
Critical navigation involves passing beneath the bridge where an enemy projectile specialist hurls corrosive substances downward. This hazardous crossing requires precise timing and awareness of environmental threats. Once cleared, continue toward the distant exit at the chamber’s far boundary.
Upon reaching the staircase summit, maintain forward momentum to confront the previously encountered projectile enemy now accessible from the bridge structure. Eliminate this threat decisively, then locate and descend the stairway on your right-hand side.
The subterranean area presents significant environmental hazards, primarily through contaminated water that rapidly inflicts the debilitating Decay status effect. Movement through these zones demands both caution and speed—lingering excessively guarantees affliction. Identify additional stairs on the left perimeter, ascend them, then traverse the damaged flooring serving as an improvised bridge across the chasm.
Within the chamber across this gap, defeat the resident guardian and claim the Archbishop’s Holy Mark resting conspicuously on the ground surface. With the artifact secured, retrace your path to Cecile’s original position.
Progress through the remaining library sections culminates in a confrontation with the area’s primary antagonist—a grotesquely transformed iteration of the Archbishop. This boss encounter represents one of the cathedral’s most demanding challenges, requiring mastery of combat mechanics and pattern recognition.
Following the Archbishop’s defeat, utilize fast travel to return to the Stargazer proximate to Cecile’s initial location. You’ll discover she has departed the premises, leaving behind a valuable compensation package for your efforts.
