The Trees of Insanity — Ch 4.3

Sent by a queen to save a dying orchard, the party climbs to five ancient trees that have stood since the Beninging — and finds them rotting from the inside, guarded by a blight that answers to someone they thought they’d left far behind. When every drink in the world is distilled from these five trunks, who would want them dead… and what secret has been sleeping in the wood the whole time? Some cliffs you climb. Some you fall from. These trees make you lose your mind either way.

Synopsis

Fresh off being flushed into the sea by The Ferryman, the party surfaces at the base of a monstrous cliff, climbs its endless stairs (skipping the Princess-Bride sword-fight at the top), and steps into the Forbidden Fruits Orchard — beautiful, and beautifully decaying. Reading the trees, Foulclaw recognizes five massive trunks at the center: The Pillars, the original trees standing since the Beninging, purchased long ago by Zen au Kouréas and tended by Castle Leary, from which every one of the Seven Deadly Sips is distilled. They’ve been strangled by a three-week Mist and blight, their fruit rotted to slime — and the moment Foulclaw carves a sample, a spiked vine coils his ankle and the whole grove wakes up hungry.

What follows is a marathon brawl against a Tree Blight, a pair of grappling Fester Vines, a yappy twig-blight “dog,” and a hooded druid — the Keeper of the Blight — who, when unmasked, turns out to be Tobiah: the mute, form-filling owlin the party once decked and doused in liquor back at El Cinede. Now he can talk (barely), and he’s been hired by Astaroth to poison the Orchard so “no one can ever pour alcohol on him again.” The fight is pure chaos — Foulclaw rides a string of nat-1s straight into Wild Magic, shrinking to a molting, invisible toddler until his own allies think he’s exploded; Nortle hoists the Keeper 50 feet up in a boiling Watery Sphere; TBD sculpts a Scorching Ray around the sacred trunks and later drops his first-ever Fireball; and Xeros, going incorporeal on his Ghost Step Tattoo, keeps sticking his head inside the trees, finding a sleeping man in each and reviving them one by one with Lesser Restoration. The Keeper goes down (spared, hot-domed unconscious), the boss Tree Blight dies with its acorns crushed, and the blight finally recedes.

With the Orchard healing, the party eats a bud from the restored purple Laranune tree — and gains Truesight: Xeros isn’t a demon at all but a teenaged boy, and everyone who loves you glows, which shocks Nortle out of his grudge over the last session’s deception and points his fury squarely at Astaroth. They charm the pathetic Tobiah, pack him off to Manni Dugal and the School of ITYS for “conversion,” and race back down the cliff to the mermaid queen Sissily. When they show her the Laranune flower, a memory surfaces and she weeps — then recognizes the journal they looted from the Ferryman’s cabin: it’s written on Scrail, her people’s scale-paper, stolen from her hundreds of years ago by an obsessed Baeden Leary. Her god Eadro forbids the merfolk any record, so she hides a secret library to reclaim what the siren takes — and reveals the gut-punch hook: the friend who also lost her memory to the Ferryman was Basil. Sissily sends them back to Castle Leary to gather their wagon of information and find Millie — who, unbeknownst to her, has already been taken by Astaroth.

🎙️ Notable Moments

00:41:47 — Climbing the endless cliff stairs to the Orchard, the table cannot let a Princess Bride setup pass — and it names the whole episode.

Nortle: The Cliffs of Insanity! Oh, we’re done. Xeros: As long as we get to have the sword fight at the top. Foulclaw: I am not left-handed. I am actually— sorry, that’s not my line. Nortle: Wait — actually you are. You ruined it.

01:07:08 — A vine draws blood and a poison save; Xeros celebrates the wound with a word nobody knows.

Xeros: In ITYS, we call it a brisk. Nortle: Sorry, I didn’t follow that one. TBD: A brisk? Xeros: When we celebrate a young man’s birth and we remove something from him — that’s called a brisk, my friends. Nortle: Umbilical cord?

01:54:07 — Mid-fight, Foulclaw's back-to-back nat-1s trigger the Wild Magic that nearly killed him once before.

Xeros: Did you just Wild Magic? Jesse — this is how you died last time! Foulclaw: I shrink. I’m baby-size out here. Freshly hatched. GM (Brin): …and now you roll invisible. It literally looks like every enemy thinks you’ve just died. Foulclaw: I just killed myself because I didn’t know how to cast the spell.

02:06:05 — The terrifying hooded druid finally reveals himself — and instantly stops being scary.

GM (Brin): She pulls off her hood — and you see this is not a she. It is Tobiah. Tobiah: I have to destroy this orchard so that no one can pour alcohol on me ever again, like you reprobates did! Xeros: (clapping from a tree) Well done, Tobiah — you can drop the act now. You just lost all credibility. TBD: The Keeper was actually kind of scary… and now it’s just a joke.

02:14:12 — Tobiah, upside-down and captured, keeps answering questions with the least interesting thing possible.

Xeros: Hey, Tobiah — did your wife leave you because of your voice? Tobiah: I’ve never been married. That’s a very odd question. TBD: This guy’s going to kill us all with his mundaneness. Xeros: You just bored me to death, my friend. Give him a token.

03:35:54 — Xeros ends the boss the only way this session could: reaching into the giant Tree Blight and squeezing.

Xeros: I reach in, grab its acorns, and cast Burning Hands. TBD: You have killed this tree by crushing its acorns. GM (Brin): You have crushed its posterity. You’ve taken the seed of blight and obliterated it. Foulclaw: It failed the posterity check. Xeros: Roll for posterity.

03:37:34 — First-time DM Brin keeps "slipping," and Steve has learned exactly which words spring the P-word jar.

Nortle: Ask me if I was baiting you. I was. GM (Brin): This place is just soaking in it — the magic. Nortle: I said “so” and “baiting”… and you took both of them, exactly as I knew you would. GM (Brin): This is my swear jar. I have a problem.

03:44:16 — Eating the healed purple tree's bud grants Truesight — and shows Nortle who really loves him.

GM (Brin): With true sight, the people who care for you glow like candlelight. Nortle: (seeing his friends blaze) …they were only trying to spare my feelings. Nortle: He needs to let go of that frustration — and direct it at Astaroth, and punch her in the throat. GM (Brin): That tracks. Yep, that tracks.

04:23:17 — Shown the Ferryman's looted journal, Sissily recognizes the very paper it's written on.

GM (Sissily): This paper it’s made of — that is Scrail. Only my people make it. This was stolen from me. Foulclaw: You mean… hundreds of years ago? GM (Sissily): I know who took it. It was Baeden. He had very strong feelings for me. He was obsessed. TBD: So it’s a diary.

04:31:37 — Nortle can't resist a Disney number inside the sea-queen's forbidden secret library.

Nortle: (bursting into song) Tale as old as time… Foulclaw: Nortle — we’re having a beautiful moment, and we’re supposed to keep our voices down in the library. GM (Sissily): If I am caught with any book, I will be severely punished by Eadro. Nortle: …I’ll leave the singing to TBD. Sorry.

Cliffhanger

The Forbidden Fruits Orchard is saved and Tobiah is packed off to church — but the real prize is a diary made of stolen mermaid Scrail. Sissily lost her memory to the obsessed Baeden Leary — and so did Basil. If the party can gather the right Memory Anchors, they can give both women back what the Ferryman took. First stop: Castle Leary, their wagon of information, and Millie — who’s already in Astaroth’s hands.
