Where is Floon?

Volothamp Geddarm asked Kafin Lowlance, Perrín Aloro and Stockmun Cay to find Floon Blagmaar. They follow some leads and end up in a Xanathar Guild hideout in the sewers, where they find Floon. It turns out he was abducted together with Renaer Neverember by Zhentarim thugs, because they thought he knew something about father's hidden gold. Xanathar Guild bandits attacked the Zhents, and abducted Floon, thinking it was Renaer.
