While Mouse recovers from his near-death acid-to-the-face experience, the party divides Garrundar the Vile's treasure with the mist dragon Thalagyrt and Galron gives a guided tour to the field trip from the Order of the Many-Starred Cloak. Mardred the Many agrees to fix up their damaged Halruaan airship and the party sets sail for the island of Ruathym to find the drifting ship formerly known as Yngvar's Thunder and discover what's in the box that Gellan Primewater was willing to pay them to recover.  Unfortunately, the barely-afloat ship is infested with a variety of spiders and some Lolth-worshipers!  Grim learns to hate spider swarms, Galron blinks in and out of the ethereal with a pair of phase spiders, Yngvar tries to hold everyone together, and that's all before the elder giant octopus attack!
