Info: Moondrop is the owner of The Common Club, a plain looking storefront hides a ramshackle inside with piles of miscellaneous maybe broken maybe partly missing items with a back room that has some magical mechanical mechanisms.
The PCs give him a copy of a tape of sensitive nature featuring Tierns. Moondrop invites them to a meeting of the Round Earth Truthers.
Moondrop trades in secrets and information and collects random items to trade for it.
