No worries, real life is a thing. 

So, if you want more info on how "flow" works in Type-Moon, Kayneth and Meltlilith's profiles have a fair amount of info on that. 

Regarding Alchemy, if you're using it for ochem stuff then that's fine, science has surpassed magecraft because science is pretty good nowadays; don't step outside the realms of reason though, I'll just trust you to exercise judgment and not think you can engineer ridiculous impossibilities. 

The gun's fine, but there will be some IC dislike from the NPCs if they catch word of you using them, namely the Church Overseer. If you don't care about him though, then no downsides.
