With the help of Anaerion's magics, Tyrien takes to the air, sweeping her way across the lake, though it's hardly a flight of fancy. While no more of it seems to have the animus to reach out for its meals, the lake and shore is still thick with foul-colored fungi of various stripes. Given Hyve's real profession, Tyrien suspects that none of it's anything she should try nibbling on.
Fungus isn't the only thing Hyve planted, however. With perspective, light, and the absence of immediate threats, the half-elf quickly spots multiple humanoid victims of the poisoner, both in the lake and on the shores.
Most of the bodies have clearly been here a long time, and their bleached bones would likely have made them more noticable before were it not for the mushrooms which have taken root along them, so that the bright white can easily be mistaken for just another variety of the nasty fungus Hyve cultivated.
On the far beach, however, Tyrien finds a corpse that is relatively intact. That is, by comparison: his flesh has clearly been the source of several meals for the rot-inducing violet fungus, but most of his black leather armor is intact, enough so that Tyrien can recognize his accoutrements as those of a Crow. His hand, shriveled as much of his flesh is, loosely grips a longsword. The blade is clearly of fine make, and has somehow collected none of the muck or decay which characterizes everything else in the cavern.
