The heroes are called to the docks to fight an incursion of sahuagin and giant crabs (and sharks, but they are in the water). After a brutal fight, the sahuagin leave, but the whole thing stinks of a diversion, as attacks happened on the river and on the docks, but only minor damage is done. Also, Regga is caught watching them, with a realistic-looking eye necklace around her neck.
The heroes then learn that the temple of Astarte is on fire. They fight a group of magmin, see a night hag disappear from the basement, and find that a hidden tomb in the secret but now exposed sub-basement is empty. The night hag seems to have struck at the temple and stolen the contents of the tomb somehow before stepping sideways out of reality.
