Adventure Three, Session Twenty Two

INT. SALLOWOAK WOODS, UNDERDARK CAVERNS - SUPPOSEDLY DAY
When we last left our heroes, they had been led by the (friendly) mind flayer named Kharthlaxi into the Sallowoak Woods, deep within the "Wet Dark" beneath the Wyrmcrest Mountain Range in Hariel Minuta. The illithid guide had previously marked his passage through the grove of "man-eating albino trees," having discovered a path through the forest that didn't involve anyone getting eaten alive. Unfortunately, the ambulatory trees had moved since then, and Kharthlaxi's path was rendered useless. The party needed a way to proceed safely. Kharthlaxi reminded the party of a cave they'd previously passed; the lair of an ancient gargantuan (and legally blind) beast known as a "Froghemoth," which was constantly hungry for pretty much anything to eat. The PCs realized that the trees of the Sallowoak had no interest in devouring their monodrone pal "Fourry," so they hatched a slightly nutty plan...
They sent Warren into the Froghemoth's lair as "bait," to lure the creature back to the Sallowoak, where then Warren traded off (tag team style) with Fourry. Fourry was supposed to run forth down the path, making tons of noise, luring the blind beast along. This way, theoretically, the giant creature would draw the majority of the ensuing tree attacks. However, the little monodrone got confused and didn't quite run off the way he was supposed to. Mangy took quick and decisive action, running off himself, attempting to lure the beast. Fourry then followed Mangy, and sure enough the trees "came alive" and set to action.
As the trees slashed at the running PCs with thorny limbs, the Froghemoth finally gave chase itself. It too was quickly attacked by the thrashing limbs of a multitude of albino, carnivorous trees. Oh, and one other thing that sort of got forgotten in all the hullabaloo... the trees all bore bizarre fruit, white and round, like pearlescent apples. These fruit allegedly had odd and random effects upon any who consumed them. During the fray, the Froghemoth, hungry as it was, ate a few of these white apples.
And the beast was blessed by the return of its eyesight!
The Froghemoth turned its attention to the back end of the party, which included Naiya and Oltorf. Oltorf defended the group to the best of his abilities, and managed to keep the beast from devouring the inheritrix. Mangy leapt upon his flying carpet and rushed through the air to rescue Naiya, who was soon bound and held aloft by the Froghemoth's tentacles. After taking a blast from Warren, the creature released its grasp on Naiya, who fell directly onto the flying carpet, saved in a nick of time! Mangy then rerouted and flew ahead of the party, looking for the exit.
Elsa, for her part, rushed ahead to join the lone and confused Fourry, and the two of them came upon a split in the path. Left or right? After seeing the mass of moving trees to the right path, and only one oversized tree to the left, she decided to take the latter passageway. She and Fourry rushed off that direction.
As they entered the left corridor (bordered on both sides by the wicked trees0, they came to get a better view of the large tree (in the center of the path). A person was hanging from its branches. A dark elf. A female qualenti. One that looked suspiciously like Teffa. Could it be just an illusion or a clone?
Eventually, the rest of the party caught up with Esla and Fourry down the left path. Warren and Mangy attempted to free the being that appeared to be Teffa from the tree she was bound to. Spindly limbs projected from Its large white trunk, some of them piercing the dark elf's skin as if they were tubes feeding some dark ichor into her body. As they grabbed her arms in response to her plea for help, suddenly her appendages transformed into twisted tree branches that instantly entwined both Warren and Mangy!
Whatever the creature was, it certainly was not Teffa. In fact, by this time, all traces of similarity melted away as the proxy form that appeared as the dark elf turned into a giant maw, slowly pulling Mangy and Warren towards it's toothy opening. It was all an illusion, a trap to catch the PCs.
Mangy used his Thunder Step to yank himself free (though it damaged him) of the tendrils holding his arm. Oltorf hacked at the roots and vines holding Warren, freeing him as well. The party continued to fight the aberration, even as the Froghemoth approached. The giant beast was beset by a bevy of trees, but it twisted its body, pulling them from the ground and wrapping them around him like spaghetti on a fork.
As the party weakened the giant tree, it made another gambit for Warren, grabbing him and completely enveloping him in a mass of plant matter, as if absorbing him. It took a combined effort from the party to free him, and they finally killed the giant tree. Immediately, the surrounding ambulatory trees, which had been watching and waiting on the fringes, started to back away. The PCs surmised that perhaps the giant dead tree was their "queen." As for the Froghemoth, Mangy cast a Web upon it, gumming it up long enough for the party to descend into an "exit," looming just ahead of them. They ran off at full speed, leaving the Sallowoak behind, but possibly with the Froghemoth right on their heels...
