In Baldur’s Gate 3, the riddle “What can silence the Nightsong?” in the Silent Library is solved by the book Teachings of Loss: The Nightsinger and, in the lore, only Shar, the Nightsinger , can truly silence the Nightsong.

Quick Scoop: Core Answer

  • The in‑game riddle answer is the book Teachings of Loss: The Nightsinger.
  • The lore answer spelled out in that book is that Shar (the Nightsinger) can silence the Nightsong.
  • Putting the book on the Riddle of the Night pedestal opens a secret chamber with the Spear of Night and Dark Justiciar gear.

Where the Riddle Appears (Gauntlet of Shar)

You encounter this puzzle in Act 2 , inside the Gauntlet of Shar , in a sub‑area called the Silent Library.

Key points:

  • The Silent Library is located south of the Faith‑Step trial in the Gauntlet of Shar.
  • The room is filled with trapped bookcases and enemies you must defeat to safely search.
  • In the center is the pedestal labeled Riddle of the Night , asking: “What can silence the Nightsong?”.

Step‑by‑Step: How to “Silence the Nightsong”

  1. Clear the Silent Library
    • Defeat the Justiciar duellists and other enemies inside the room.
 * Avoid or disarm **gas pit** and bookcase traps if you want to loot safely.
  1. Find the Correct Book
    • Search the bookcases along the walls.
    • The book Teachings of Loss: The Nightsinger is found on the northeastern bookshelf (often described as the second bookcase on the right / NE side as you enter).
 * Other books are just lore; only this one actually solves the puzzle.
  1. Use the Riddle Pedestal
    • Interact with the pedestal named Riddle of the Night in the middle of the room.
 * Open your inventory and **place “Teachings of Loss: The Nightsinger” into the slot** , then confirm.

 * A hidden wall behind the pedestal opens, revealing a treasure room.

What You Get for Solving It

By “silencing the Nightsong” via the riddle, you unlock a small treasure chamber.

Rewards include:

  • Spear of Night – a key artifact later tied to Nightsong’s fate and Shadowheart’s Shar‑driven choices.
  • Dark Justiciar armor pieces , such as:
    • Dark Justiciar Half‑Plate
    • Dark Justiciar Helmet

These items are especially thematic and mechanically useful if you’re steering Shadowheart toward becoming a Dark Justiciar , Shar’s elite warrior.

Lore Angle: What Can Truly Silence Her?

Inside Teachings of Loss: The Nightsinger , there’s a line that essentially states that only Shar, the Nightsinger, can silence the Nightsong.

  • This ties the puzzle thematically to Shar vs. Selûne , loss vs. light, and Shadowheart’s internal struggle.
  • The riddle answer is, therefore, both a literal solution (the book) and a lore answer (Shar/Nightsinger).

Forum & “Worst Puzzle” Discourse

On forums like Reddit, players frequently complain that “What can silence the Nightsong?” is one of the most confusing or least intuitive puzzles in BG3.

Common sentiments you’ll see:

  • The riddle feels too vague , since many players expect a poetic answer like “death,” “silence,” or “sunrise,” not a specific book title.
  • Some expected the solution to tie directly to their moral choice with the Nightsong later, instead of a mechanical book puzzle.

A typical frustrated take looks like:

“I tried every poetic answer under the sun and it turns out it’s just a very specific book on one shelf.”

Still, guides and Q&A posts have made it a trending mini‑topic whenever new players hit Act 2, especially after big patches or platform releases in late 2023–2025.
