Military action
Toan, Cedric, and Tarksson check out the old Temple of Yenna to see if the Venumbra Cultists are still there. They are not. They then head to the Symphony Guard Headquarters to interrogate Tanozall and Syr'Cap. They don't put up a fight, and tell them everything they want to know. At a certain point, Venumbra's forces arrive to kill Syr'Cap and Tanozall, consisting of numerous undead monsters, several formed out of the corpses of Busiris, Karlt, and Dhrakus. They fight, and several Symphony Guards are killed, as is Tanozall.
