<aside> <img src="/icons/info-alternate_gray.svg" alt="/icons/info-alternate_gray.svg" width="40px" /> Gallery view in databases is your friend if you want to build a visual wiki of story characters. A character wiki is great if you're a writer, D&D master or just for fun if you're a big fan of something (like Pokémon!).
</aside>
Set up a page and add an in-line Gallery database. Create a character template in your database to quickly add characters with a uniform page layout. Each character's page can include whatever information you like, but especially if you're using this to brainstorm and plan a story you're writing you should consider what questions to ask yourself about your characters.
Use your template to populate the database with characters. Make sure to include an image to represent the character, either as the page cover or uploaded to a Files property. Set the gallery database to display the images and you have a beautiful wiki to reference whenever you need.
If you're writing fantasy or sci-fi you can have wikis for other things too, like places that exist in your world, creatures that live in it, and materials and artifacts. You can use a Relation property to connect things even between databases, for example a character to the location they grew up in.
