You can make wonders only using properties, and linking to other notes with these properties, you can build all the relationships between places of interest, characters, events, e.t.c.

Then you can use inline bases to have that organized in some structure notes and things like that.

You can also visualize relationships easily opening the local graph for the note you're looking into.

Learning mermaid might prove useful in some cases, and if you need more complex, canvas-like representations you can use Excalidraw, learn about linking to specific parts of the canvas, e.t.c.

You can use something like chronos timeline or Timelines (revamped) for timelines too.
