The Palace of the Green Dome stands as one of the most restricted and intriguing locations in Assassin’s Creed Mirage, housing a vital Lost Book that players can’t grab until deep into the narrative. This collectible, known as Al-Sikkit: Diwan Abu Nu’as, contributes to Basim’s intellectual growth and unlocks Enkidu Tokens for upgrades. Accessing it demands specific story progress, precise parkour, and stealth savvy amid heavy guard presence.
Why Lost Books Matter in Assassin’s Creed Mirage
Lost Books are scattered historical texts that Basim studies to enhance his skills. Collecting all seven grants permanent buffs like increased health or throwing knife capacity. The Palace book is the final one for many players, tucked away in Round City’s opulent core.
- Core Benefits: Each book provides an Enkidu Token and a unique upgrade.
- Total Count: Seven books across Baghdad’s districts.
- Tracking: Use the Enigma page in the codex or buy maps from cartographers.
Prerequisites for Entering the Palace
You must advance to the late-game quest The Serpent’s Nest or equivalent storyline beats granting Round City access. Earlier attempts hit impenetrable walls—guards swarm, and doors stay locked.
| Requirement | Details |
|---|---|
| Story Progress | Reach Round City missions; complete palace infiltration. |
| Skills Needed | Parkour mastery, throwing knives, stealth kills. |
| Recommended Gear | Smoke bombs, high outfit rank for blending. |
Navigating Round City to the Palace
Round City, Baghdad’s administrative heart, buzzes with patrols. Synchronize the nearby viewpoint for map clarity, then slip toward the palace’s eastern flank.
- Enter via the main southern gate during your story mission.
- Stealth through courtyards, assassinating archers on walls.
- Locate the prominent locked door on the palace’s inner hallway—this is your marker.
From this door, pivot outside. Guards thin here post-mission, but stay vigilant.
Step-by-Step Path to the Lost Book
Once outside the locked door, execute this route precisely:

- Spot the Hook: Face the palace wall; climb to the protruding metal hook above.
- Balcony Drop: Swing across, drop onto the wooden balcony below. Time it to avoid patrols.
- Window Entry: The window is now unobstructed—mantle inside the high room.
- Grab the Book: It’s on a central table amid scrolls. Interact to collect.
- Exit Safely: Another door loops back to the main palace corridor.
This room holds minimal loot beyond the book and a note, but it’s a completionist’s gem.
Common Pitfalls and Fixes
Players often bash the locked door in vain or miss the balcony due to poor visibility.
- No Key Exists: Ignore key hunts; the exterior path bypasses it.
- Story Lock: If inaccessible, fast-travel after Serpent’s Nest.
- Guard Overload: Use rooftops or distractions like fireworks.
