Doyen Sump

• Cautiously brilliant, with a tendency toward underplaying his talents
• Speaks in circuitous, self-deprecating tones to deflect scrutiny
• Has burned through at least three separate personas, each with conflicting guild affiliations and city of birth

In combat, Doyen plays the long game: support, sabotage, and survival. He creates traps out of furniture, solutions out of poison, and distractions out of nothing at all. His alchemical formulas are often unpredictable—either revolutionary or catastrophically mislabeled.

• Unclear how many organizations he has worked for, but at least one Harper agent has files on him
• Considered “mostly honest” by Jackob and “delightfully suspicious” by Ambrose Rosznar
• Has not shared his real name with anyone, outside of the Hype Squad—even the Librarian has only guesses

“They played the Grand Game to its end—
and discovered that the final move was never theirs alone.”
—The Librarian

The Hype Squad’s role in the Grand Game concluded in a night of masks, broken pacts, and unanswered questions. What transpired beneath Waterdeep reshaped the city’s balance of power, scattered its conspirators, and left scars that have yet to heal.

Much remains obscured—by design, by magic, and by those who survived.

“History will name winners and losers.
The truth is less orderly.”
—The Librarian

Doyen Sump is either a fraud pretending to be clever, or a clever man pretending to be a fraud. Both possibilities are dangerous. But let no one mistake this: when the moment arrives, he does not run. He prepares. And then he detonates something behind him.
