What the party knows, as of Session 2 Recap - Three to the Dawn.
The criminal organisation that caught Varys as a young thief, trained him instead of jailing him, and used him for dishonourable work until he ran. He has been hiding from them inside the Guild ever since.

Their marks

  • Hair tied in a run of small knots. One of the men who died in the alley ambush in Godshome wore it, alongside acolytes of Gruumsh.
  • Thieves’ cant, burned into crates, which Varys can read.

Where the party has seen them

  • The alley in Godshome: one Ledger man among the priest of Gruumsh’s crew.
  • Bitter End: their mark and precious cargo on a crate holding a drugged sleeper (The Sleepers in the Crates), one of three bound into the Bitter Market.
  • The Valley of Lost Bearings: their mark on a water barrel fallen from a caravan, found half buried in a salt flat deep inside the valley.
