What are entity relationships?

Relationships in Mythos allow you to create parent-child hierarchies between entities. This helps you organize complex worlds, show membership, and group related elements.

Note

Available in: Book Workspace only

Note

"Parent-child" is organizational, not familial. It simply means one entity belongs to or is part of another.

Creating relationships

To create a relationship:

Open the parent entity's profile
Go to the "Relationships" tab
Click "Add Child"
Select or create the child entity

Or from the child: Open child entity → Set "Parent Entity" field → Save

Relationships can be inverted if you created the parent/child relationship incorrectly.

Viewing relationships

Relationships are visible in entity profiles only—there's no visual graph or map.

To view an entity's relationships: Open entity profile → Relationships tab → See:

Parent entity (if any)
Child entities (if any)
Sibling entities (entities with the same parent)

Benefits of relationships

Organization

Keep related entities grouped logically. Instead of a flat list of 50 locations, organize them by kingdom, province, and city.

Color inheritance

Assign a color to a parent entity and all children inherit that color—useful for visual grouping in your manuscript.

Example: Assign blue to "The Empire" and all cities in the empire are highlighted in blue when mentioned in your text.

AI context

Add a parent or child entity from Add → Mythos entities in AI Chat. The assistant receives the selected entity’s AI-visible profile fields.

Example:

Tell me about The Guild and its members based on the added profile.

If membership details are stored in AI-visible profile fields, the assistant can use them. Add other member profiles or relevant manuscript text when those details are not present.
