Fionn: Tony Curran
Fionn is appointed the Keeper of the Keys, but longs for something greater than arguing
with Centaurs and breeding Thestrals. Will he find that something more in Helga?
Hrognoth: Russell Tovey
The Smith of Hogwarts, Hrognoth has deep feelings towards Helga. But he's quite dreadful at
making them clear to her...
;
Mimsy the Younger: John Cleese

Mimsy is a nonwizard-born knight who is instrumental to the security measures at Hogwarts. He
sees Godric as something of a protégé, but worries that the man's rashness might also be his
undoing.
Pan: Aidan Turner(I mean, of course Aidan Turner plays a Centaur.)

Pan is the leader of the Centaurs, and not at all happy with the building of a castle so
close to his forest. But will efforts to protect his herd go too far?
I envision this as taking place 5-6 seasons. Perhaps with time jumps.
Assorted plot points (expanding on what has been said above):
- Hogwarts is founded.
- Negotiations with Centaurs are discussed; the Founders differ on how to handle it. Helga, Bronwyn, Eoforhild and Salazar (believe it or not) feel that more compromise must be made. Godric, Rowena, and Ravenclaw see them as being upset over losing land they were not even occupying (which has some truth) and that enough compromise has been made, given that they have the forest. Mimsy initially agrees with the latter, but begins to see the former's points. Fionn is of two minds... until he begins to see the Centaurs as hurdles, regardless.
- Ravenclaw grows increasingly jealous of Rowena, and attempts to undermine her. The only one who falls for it is Helena, who adores her father and wants to please him. Ravenclaw eventually leaves, claiming that there is trouble at home (but everyone knows this isn't true). Rowena is heartbroken; Helena blames her mother.
- Balvard's obsession with Helena is also wearing on her. She refers to him as "that bloody baron" - to his face, no less.
- Salazar, meanwhile, begins to grow more and more suspicious of letting in children of non-wizards. He believes that at the very least, strict measures must be taken. A chamber, perhaps, with a creature that will attack anyone who might betray
them...
- But that's not all that occupies him. Weary of her daughter hating her and her husband's absence, Rowena begins to take comfort in Salazar, realizing that she is in love with him. She confesses this to Helga, claiming that Salazar's wife doesn't love him and that "adultery, under certain circumstances, is hardly the worst sin." Helga puts her to shame, and they go several episodes without speaking a word to each other.
- Fionn, tired of sparring with Pan, kills him in a fit of rage. (Sorry, Aidan Turner.) This sets off a conflict that almost ruins Hogwarts, and causes even more tension. Salazar and Godric argue more, Salazar goes deeper into dark things even Eoforhild has trouble reconciling, and Helga tells Fionn she no longer loves him. How can she?
A battle sees the deaths of Mimsy and Fionn, and an irreparable argument between Salazar and the other Founders. This would be a season finale, perhaps the second.
- The third season begins with the birth of Godric's first child. But he is more focused on trying to repair relations between
the wizards and witches of Hogwarts and the Centaurs - something Bronwyn points out should have been his goal from the beginning. He knows that the future of his school is uncertain, and puts responsibility on himself. Helga, meanwhile, is devastated and confused, mourning a man she wishes she didn't still love.
Meanwhile, Helena - now sixteen - is growing wearier and wearier of Balvard's advances. She also feels substantially less gifted than her mother. One night she finds the Diadem, and steals it. She leaves a note on her mother's pillow saying that she is done being a mere daughter. Rowena is understandably devastated.
- Adding to her devastation is the departure of Salazar. This shakes the whole group; everyone blames themselves, but especially Godric and Balvard, the latter of whom believed himself to be something of a protégé. Eoforhild says tearful goodbyes, and tells Rowena that she never really hated her - but rather, greatly envied her.
Rowena later tells Godric that she wishes she'd been born far more ordinary, because envy has destroyed everything: her marriage to Ravenclaw, her relationship with Helena, and it earned her disdain from Eoforhild. Godric assures her that it is other people's choice to act on those feelings, and points out that many more people in her life chose not to.
- Helga begins to find love in an unexpected place: Hrognoth. She is delighted when he proposes.
