Panthem Abbey in Hell Is Us becomes accessible through the Keystone of Ecstasy questline. Initially blocked in the Acasa Marshes, the abbey only opens after players complete the Lake Cynon chapter of the game.

Steps to Access Panthem Abbey

• After finishing Lake Cynon, fast-travel to Acasa Marshes.
• Navigate to the abbey’s eastern side and locate a large mountain passageway (visible as an open doorway).
• Follow the hallway beyond the entrance to encounter Abbot Jaffer—engage with him thoroughly to advance the quest.

Abbey’s Role in the Story

Speaking to Abbot Jaffer unlocks the National Library of Lethe, where players begin:

• Solving environmental puzzles
• Collecting quest-critical items
• Progressing toward obtaining the Keystone of Ecstasy

Note: The abbey cannot be bypassed or entered early—it’s mandatory for story progression.
