Summary
A cute story I wrote to fill in a lot of gaps within the epilogue of Season 2, with a lot of distractions, particularly with Huntress wizard, Finn, and Farmworld, wanting more closure and information about them. Other than that, this is a Fionna and Fennels story on how they get together during the epilogue and also what they do behind closed doors.

Summary
Hunter was always perceived by others to be the exception, no hybrid in existence had ever been so level headed and kind. No "strange" tendencies, no "sick" urges. Never a threat. Never a problem, and they believed it too.
Until they met her.

Summary
There are three rules in summoning: No demon fighting, no contract breaking, and absolutely no falling in love with your demon.
Bonnibel Bubblegum is a freshman at the Ooo Institute of Magic, embarking on her demonology major. Impatient to get started, she summons a demon outside of class, locking her in a contract with a demon that just so happens to be the princess of hell. Circumstances force her to spend time with her academic rival, Gary Gumball, because he's in trouble for the same reason she is and it turns out that he's bound to her own demon's twin brother.
Turns out the king of hell really doesn't want his children bound to a pair of mortals, and what was once a foray into academia turns into a fight for survival against the forces of hell itself as the king extends his claws to get his children back.

Summary
In a divergent timeline, what if someone who wasn't supposed to be paying attention, did, someone who in most scenarios wouldn't have gotten involved, got into the mess by chance.
Ever since the summoning of Golb, Bonnibel Bubblegum had been trying to tackle her underlying fear of a cataclismic event that could affect the land of Ooo. When she detects a signal far away late at night, she just thought a quick check wouldn't be much and soon enough she could be back home with Marceline after another long day of work, but oh boy was she wrong, she gets immersed into a mess she couldn't even imagine, creating a divergent new story.
(Esentially an alternate timeline in which Princess Bubblegum, joins Simon, Fionna and Cake, in the adventure of their lifetime reshaping the events of Fionna and Cake Season 1 and beyond).

Summary
Domesticity isn't seen as natural. It is a part of human intervention, humans playing god.
Domesticity isn't for Huntress, neither is it really for Fionna either. They both got too close, though, and their own walls are taking the brunt of it.

Summary
We all know that life goes on and that the world doesn’t stop for anyone, even when keeping up becomes harder and harder.
Fionna is no longer the warrior who saved lives with a smile. Now she struggles to hold on to a job and not completely lose that sense of heroism that only survives through helping others.
In one of the heaviest moments of her “normal” life, an unexpected encounter arrives: the Huntress Wizard.
Together, they will discover that Fionna’s world still holds more magic than it seems, that she can be much more than just another version of Finn, and that the Huntress Wizard doesn’t have to face everything on her own.And perhaps they, and all of Ooo, will also come to understand that there are people who are not easy to save.
Welcome to a Fionna/Huntress Wizard fanfic!
