Why

Obsidian's built-in graph shows every link in your vault, all at once, undifferentiated. Relations shows just the connections you care about — the ones you've explicitly named — and shows them with meaning: who's allied with whom, who's married, who's a rival, who descended from whom.

Useful for:

• Worldbuilding — factions, organisations, cities, gods, dynasties
• Fiction writing — story casts, dramatis personae, conflict webs
• TTRPG campaigns — NPC networks, allegiances, rivalries, family lines
• Historical research — genealogies, political networks, succession charts
• Anything else where you've got a cast of linked notes and want to see it

Install

Via BRAT (recommended)

BRAT is the standard way to install community plugins that aren't (yet) in Obsidian's official catalogue. It also handles updates automatically.

1. Install the Obsidian42 - BRAT plugin from Settings → Community plugins → Browse.
2. Open BRAT's settings and click Add Beta plugin.
3. Paste this repository URL: https://github.com/Obsidian-TTRPG-Community/Relations
4. Click Add Plugin. BRAT downloads it and installs.
5. Settings → Community plugins → enable Relations.

BRAT will notify you of updates and apply them when you click through.

Manual install

1. Download main.js, manifest.json, and styles.css from the latest release.
2. Drop them into <your-vault>/.obsidian/plugins/relations/ (create the folder if it doesn't exist).
3. In Obsidian, Settings → Community plugins → enable Relations.

Quick start

Add a portrait and some relationships to any note's frontmatter:

---
npcimage: "[[merlin-portrait.png]]"
ally:
  - "[[Arthur]]"
spouse: "[[Nimue]]"
mentor:
  - "[[Arthur]]"
family:
  - "[[Morgana]]"
---

# Merlin

The court magician of Camelot…

Open the graph from the users ribbon icon in the left sidebar, or run Open Relations graph from the command palette. Click any node to open that note. Right-click for open in tab / open in pane.

The view has a Full / Active note toggle:

• Full — every connected note in the vault.
• Active note — the currently open note plus everyone within N hops (configurable, 1–6).

Embedding a graph in a note

Use a fenced code block with the relations language tag anywhere in a note:

```relations
size: small
depth: 1
```

[!TIP] Don't want to type the fences? Open the command palette and run Insert relations code block to drop a bare block at the cursor, or Insert relations code block (with all options) to get every option pre-filled as commented-out lines you can selectively enable.

[!NOTE] ```npc-graph works too as a legacy alias if you have older notes from before the rename.

Inside callouts and infoboxes

This is the killer feature for character sheets. Drop a relations block inside any callout — [!info], [!note], the popular ITS Theme infobox, the Fancy a Story fas-infobox, anything — and it auto-renders in compact "mini" mode: smaller portraits, no border, transparent background, tightly packed.

> [!infobox|right]
> # Merlin
> ![[merlin.png|cover hsmall]]
> ###### Relationships
> ```relations
> ```

The empty block uses sensible defaults — direct neighbours of the host note, mini size, depth 1. You can override with explicit size: small or size: large if you want the bigger format inside a callout.

All code-block options

Family-graph mode

A focused family view for the host note. Generations are aligned in horizontal rows — parents above, the focus and any partners on the middle row, children below — with edges styled to distinguish marriage from informal partnership and parent from child.

# Arthur's note
parent:
  - "[[Uther]]"
  - "[[Igraine]]"
spouse:
  - "[[Guinevere]]"

```relations
size: large
family-graph: true
```

What you'll see

• Solid line between two people = declared marriage (any pair-flagged relationship like spouse)
• Dotted line between two people = informal partnership — automatically inferred when two people share a child but have no declared marriage between them. You don't have to model this explicitly; just declare the child's parents, and a partnership line appears
• Arrowed line = parent → child (genealogy edge), pointing in the natural reading direction
• Declared spouses go to the LEFT of the focus, informal partners to the RIGHT — a deterministic visual convention so the chart reads the same way every time, regardless of which order Obsidian indexed the frontmatter
• Only family appears — ancestors, descendants, partners. Allies, enemies, mentors, and other relationship types are hidden so the family structure reads cleanly. Switch to the regular Full or Active-note views to see those

Use scope: full to see everything

By default family-graph builds a neighbourhood around the active note. To show the whole vault's family in one view, add scope: full:

```relations
size: large
family-graph: true
scope: full
```

Relationship types

Configure types in Settings → Relations. Each type has a name (= frontmatter property name), a color, and a set of behaviour flags:

Defaults shipped:

The palette is chosen so each line is distinguishable from every other at the typical edge widths used in the graph view, on both Obsidian dark and light themes. Greens read as positive, reds and oranges as adversarial, gold and bronze as kinship, pinks as romantic, violet for the asymmetric mentor relationship.

Rename, recolour, add, or delete freely — they're just defaults.

Portraits

The portrait property name is configurable in settings (default: npcimage). Accepted forms:

npcimage: "[[merlin.png]]"                     # vault wikilink (recommended)
npcimage: "Assets/Portraits/merlin.png"        # vault path
npcimage: "https://example.com/merlin.png"     # external URL

The plugin uses Obsidian's resource path resolution, so vault images load even if your vault isn't web-served.

ally: "[[Bob]]"                     # single
ally: ["[[Bob]]", "[[Alice]]"]      # YAML inline list
ally:                               # YAML block list
  - "[[Bob]]"
  - "[[Alice]]"
ally: "[[Bob]], [[Alice]]"          # comma-separated

Building from source

git clone https://github.com/Obsidian-TTRPG-Community/Relations.git
cd Relations
npm install
npm run build

Then copy main.js, manifest.json, and styles.css into <vault>/.obsidian/plugins/relations/ and enable the plugin.

Roadmap

• Filter chips by relationship type / tag inside the graph
• Edit relationships directly from the graph (right-click → add ally)
• Per-relationship metadata (notes, strength) via richer frontmatter
• Group/cluster by faction tag
• Export graph as PNG/SVG
