I'm always sad that people don't talk much about tactical breach wizards so I decided I'm just gonna share all my bullshit in the hopes that someone else cares so anyway here's my rion head cannons that vary wildly in depth and seriousness.
He's allergic to chocolate (as a dog and as a human)
Contrary to that he's only color blind as a dog (bc I think it fits to make it so he can literally only see red when he's human (((and I like to think it's possible that the first time he ever saw the color red it was from his owners blood))))
His music taste is all girl pop like Chappell Roan and shit (this is also most of Jens music taste and she's BAFFLED when she finds this out)
He unlocked probably like 10ish years before the game takes place, most of that time he was working pretty closely with the druid mafia
Post cannon he actually keeps kind of in touch with banks but absolutely ghosts everyone else
He's gay and aromantic (but I don't think he knows what aromantic means or really gives a shit he thinks thats how everyone is)
He's had that collar since before he unlocked and by this point it would def be a vessel, but also he wouldn't ever give it to someone else so it's just kinda useless (also considering his craft is just to turn into a human, I have no idea what his vessel would do if he ever did give it away)
All of his outfits except for the default one and the wiztac one simply Are Not Cannon. He would NOT fucking wear that.
He knows how to do a bunch of ritual magic (like glyphs and shit) that he learned from the druids (and I think that the druids use a ton of weird magic shit and looking back it makes a lot of sense that they would be the ones working hardest to militarize mana because that's absolutely their vibe)
This isnt about rion but overall I think there's kind of a lot of magic that can be done in that world that isn't necessarily done through craft/unlocking, but the vast majority of it is done through complicated rituals and/or take really specific materials (like jens scrying spell in act 1). This is where a lot of the in-game abilities that aren't directly related to craft (like most of Zan and Rions abilities) come from, but they're really complicated to figure out, especially without the right resources and knowledge and it takes a lot of skill and practice, which is why stuff like mana is the more common option even though it's way fucking dumber
I think he's deeply bad at reading people regardless of what form he's in and when he's a dog, that leads to him being way too trusting but when he's human he just overcorrects into not trusting anyone because he still doesn't have a radar for who's gonna fuck him over
He and Jirin Wexler fucked
He regrets telling banks about how he unlocked but only because she stops giving him cigarettes as a dog after that :(
He's deeply deeply touch starved and when he's human he just gets over it but when he's a dog and around people he's comfortable with, he gets really clingy (which is super weird for people who don't know that he's literally just a dog)
This isn't a head cannons bc you can tell just by looking at him but hes constantly trying so hard to look cool and he fails pretty miserably a lot of the time
This is also literally cannon but I have to highlight the fact that he dyes his hair (and more importantly his fucking EYEBROWS) to match the way he looks as a dog, I think it's crazy that he puts in THAT much effort for something so stupid <3
If anyone else has any other head cannons (about rion or anyone else) I'd genuinely love to hear them, I'm always sad about how few people I see talking about these incredible characters
