Having dispatched of Langderosa Cyanwrath, Pubert decapitating him with a final mighty blow of his greataxe, the team delivers the head to Frulam Mondath, who is still securely tied up in her chambers. You also manage to safely open an obviously trapped chest within this temple room as Brehanna had secured Frulam's key when previously searching her papers and maps. This must be the small bit of treasure she mentions in a note that Rezmir (whoever that is) allowed her to keep when the rest of the gold and jewels were taken from the camp northward.
Continuing east into another section of the cavern, you do very brief battle with a small group of Kobolds and a pair of Guard Drakes whom you discover were guarding three black dragon eggs - the very eggs, you suspect that Leosin requested you try to find if possible. At 150# apiece, however, you leave them in place for the time being with plans to return for them after attempting to clear the caverns.
Moving on to the western side of the cave you stumble into a barracks of Kobolds, included winged ones which you had not known existed until now. Dispatching them with relative ease, you decide to return to Frulam's chambers, which you know are secure, to take a short respite after having had no less than four battles since your last long rest.
