Somewhat Inspired by hailingstorm’s 18 year old Carl au
The idea of a younger Carl has been floating around in my brain for a while, here’s my own twist on it,
what if the 18 year-old Carl and Donut gained a reputation very similar to Lucia mar? not the same issues, but reputation.
In this one, a few details would be slightly different.
for one:,Carl would’ve moved out at 18 and moved in with his girlfriend (still Beatrice) She likely either lived with her parents or is one or two years older than him,
Most of the dungeon would play out very similar up to donut being transformed, in this AU, Donut and Carl’s dynamic is going to be very different
The first big change I’m making is that donuts charisma has a major effect on Carl,
it’s not the same as Lucias relationship with her dogs,
Donut is still a child. Who wants childish things, if she ask Carl for something unreasonable he’ll refuse, and the charm will be broken for a while, but if she asks him to kill a room full of goblin babies by pressing the detonation, that charm will override his very weak and fragile 18y/o sense of morality,
the justification, for this is wisdom is a stat that counters, charisma, and Carl lacks wisdom in his younger years
In the original series, Carl had a mentoring role for doughnut for a while, he would help her understand how to process the situation they were in (the mask speech at the end of books 6) and was generally the voice of reason to her irrationally, (with plenty of role reversal sprinkled throughout)
In this one, neither are going to be mature, therefore they are both twice as reckless, and both will have a deep distrust of any adults, and a undeveloped sense of morality, between Beatrice and Carls parental issues, plus frank and Maggie, (and their daughter who in this au Carl receives killing credit for) this issue becomes devastating
This becomes an issue When they run into the medowlark folks, who practically begged them to join their team. They see a cat who’s only been sentient a few days old. And an 18-year-old, whose life before the crawl was obvious messed up someway. And is unusually attached to the cat and oscillates between older brother like and borderline servile at times
Carl will be a player killer in this au, will receive killing credit for Frank and Maggie’s daughter, and as a result donut will have killed the guy who peed on the wall (it’s only fair. I got a skull too!)
They will have also succeeded in killing the rage elemental, instead of playing it safe, they risk it and timed the explosion correctly, this could result in a celestial box and something like Carl getting his gloom wraith phase early 
Seeing Carl killed the rage elemental and gain its abilities, would have finally push the medowlark to stop trying so hard to get him to join their team, and be a bit more afraid of him, Carl does not take this well and refuses to use it around them, resulting in the fight against the ball of swine playing out very similar,
I’m probably going to do an update to this AU to finish flushing out book one,
And a part two for the next book, etc.
two notable changes will be mordicais relation with the group (was very structured and temporary as a game guide so a lot of the relationship would be similar) and Carl gaining the Charisma necessary to break out of donuts subtle charm
If you guys have any ideas on what to add or tweak to this AU please please please let me know, the series is huge and has a lot of potential for varying paths.
