Sorry for a question again. I don't feel this one is new topic worthy, but I don't know where to ask without being a nuisance
Is it bad storytelling to have your detailed world-building (lore, history, systems, etc.) dominantly told in extra content instead of the story .
Of course I don't rely completely on it; it's just like in my story I showed that cucumber and bitter melon have different taste, but in that extra I go in details about why and how they have different taste with their history of cultivation and taxonomical classification. For more note, I'm the type of person that don't like too much explanations in the middle of the story because it's unnatural and disturbs the flow.
I'm planning to make a more detailed world-building explanation of the system of magic in my series as one of extra contents, given that I offer nothing for Inksgiving. I don't know, insecurities just creep in the back of my mind. I can hear the "Oh, this dumb bitch don't have adequate skill to convey and implement her world-building components in the story, so she has to make extra!" inside my head, and I wonder am I really that bad.
So how much is the limit of actually giving extra information, or being unskilled at world-building? Is having an extra is bad idea?
