One of Fern’s favorite memories is of Heiter telling him she’d better do as Frieren says, because if she’s bad, he’ll haunt her after he dies. She takes that to mean she’ll just get to see him, so he flips it around: if she’s a good girl, he may just come and visit her.
She wakes up leaning against Frieren as their wagon arrives at the next village on their journey. There, they hear reports of the villagers seeing the ghosts of loved ones, appearing as they did in life. While that rules out the undead, it doesn’t rule out the threat to the villagers.
While Frieren is fine moving on in the morning, Fern insists they help, as “unlike” her master, she’s a good girl. So they head into the forest to investigate, and find evidence of magical use; specifically illusion magic. Frieren IDs the one behind the “ghosts” as an Einsam.
An Einsam uses the loved ones of its victims as bait, though she assures Fern that the illusions don’t affect mages. And yet when the forest suddenly grows misty and a ghostly Heiter appears before Fern, she freezes. Even knowing it’s an illusion, the Einsam also uses her memories and his past words against her, which Fern notes is pretty damn cruel.
Frieren, who has so many centuries under her belt, is less taken in by her ghost, but she is surprised and a little bemused that it’s Himmel now instead of her old master Flamme. For an unchanging immortal elf, something like this suggests she’s changed after all.
When she uses her magic (which really packs a punch, both visually and aurally), it also snaps Fern out of it. When she sees the true form of the Einsam, she follows her master’s attack with one of her own. The monster is defeated, and the village is safe.
Frieren and Fern have both lost people dear to them, and there are times when they want nothing more than to be reunited, even if they know that’s impossible (at least until they reach Aureole).
Their encounter with the Einsam (German for lonely) tugged at that longing, weaponizing it against them. But while they must be vigilant, they can’t close themselves off from the love they still harbor for the departed.
When their travels take them to the Rigel Canyon in the Central Lands, they encounter a red solar dragon sleeping beside its nest. Frieren notices a grimoire in the nest that she wants, so she has Fern fire an attack at the dragon, only for it to have absolutely no effect.
Frieren’s reaction to this is basically “Huh, they really are tough” and indicates that the proper course now is to run. The resulting chase scares the living daylights out of Fern, and when Frieren says if they repeat the cycle enough they’ll eventually prevail, Fern isn’t having it.
The solution to their problems is to add a party member: specifically, front-liner; a warrior. Eisen told Frieren that a town in Riegel Canyon is where she can find one: Stark, his former apprentice. They’re approached by tiny old lady, who for once doesn’t want them to clean a statue of Himmel.
She leads them to Stark, who is playing with some kids. Stark is the hero of the town for standing his ground against the dragon, so surely he’s front-liner material. But while he’s warm to the kids and their grandma, he’s cool to Frieren, who after all riled up the dragon.
He’s also unimpressed with her reason for retrieving the grimoire from its nest—for no particular reason, but simply because it’s a hobby. We catch a glimpse of a memory in which Himmel praised her for her weird spells, and she says that’s the reason if he needs one, but he’s still dubious.
That’s when we learn why Stark hasn’t defeated the dragon he stood up against: he’s not the fearless hero the townsfolk believe him to be. He only “stood his ground” because he was too terrified to move, and the dragon departed on its own and has stayed away on its own.
As Stark cries and tugs at Frieren’s hem, a disgusted Fern says he’s “no good” and they should find another warrior. But Frieren still gives Stark the night to think over joining them. She’s convinced he’s the man for the job.
That night, after dinner (and we get some pretty delicious food sakuga), Frieren heads off to bed, but suggests Fern go check out what Stark’s up to. There are loud thunderous booms coming from the canyon, and when she reaches the location where they met, Fern sees that the sheer gap between the cliffs was caused by him, rending the cliff asunder with his axe.
Back before they left Eisen’s Frieren got the skinny on Stark: he was the only one to flee when his village was attacked, which made him a coward, but also kept him alive. Eisen, who saw that coward in himself (he apparently wasn’t around when his loved ones were killed) decided to teach him everything he knew.
Stark may well still be a coward, but he now possesses the skills and tools to protect others, should he wish to. He certainly wanted to defeat the dragon, but wasn’t strong enough alone. With Frieren and Fern backing him up, perhaps he can prevail, both in becoming the hero the town believes him to be, and gaining a little courage and confidence.
