You're looking at a map of every connection Brandon Sanderson has drawn between the people, places, and powers of the Cosmere -- built from 16,282 of his own answers to fan questions.
Each gemstone is an entity he's discussed. Each thread between them is a connection he's made -- two topics mentioned in the same Q&A. The bigger the gemstone, the more he's talked about it. Kaladin blazes large. Geranid, less so.
Five gemstone types, five kinds of Cosmere knowledge:
The bar at the bottom labeled Embeddings is where things get interesting.
The base graph only shows explicit connections -- entity pairs that were literally tagged together in Arcanum's database. But Brandon often discusses an entity without it being formally tagged. He might answer a question tagged only "Allomancy" but spend half the answer talking about Preservation.
The embedding system reads the text of every Q&A entry and uses AI similarity matching to find these hidden connections. Press Apply and new dashed amber lines appear -- connections the tags missed, but Brandon's words reveal.
Press Tune to control how aggressively the system discovers connections:
| Control | What It Does |
|---|---|
| Calibration Percentile | How confident do we need to be? Lower = cast a wider net. Higher = only the most obvious discoveries. At 10, a Q&A about "Investiture mechanics" might get tagged with Preservation. At 50, only entries that practically name-drop Preservation would qualify. |
| Min Specificity | Filters out hub entities that match everything loosely. Higher values only use focused entities. "Allomancy" appears in hundreds of entries and matches everything -- it gets filtered out. "Lerasium" is specific enough to produce meaningful connections. |
| Confidence Margin | When multiple entities could match an entry, how close does a runner-up need to be to the top scorer? An entry scores 0.82 for Preservation and 0.79 for Ruin. With margin 0.05, both pass (gap is only 0.03). With margin 0.01, only Preservation is kept. |
| Min Edge Weight | How many shared entries do two entities need before we draw a connection? Higher = fewer, stronger lines. At 2, a single coincidence isn't enough -- entities must co-occur at least twice. |
| Must-Bridge | Only tag entries that already mention something else. Prevents orphan discoveries floating in the void. An entry with no existing tags won't receive an implicit tag, since there's nothing for it to bridge to. |
After pressing Apply, click Review to see every implicit tag the system discovered. You can sort by confidence score, confirm tags that look right, reject false positives, and save your reviews to a file.
Use the Explicit / Both / Implicit radio toggle to switch which edge layer is visible -- see only the original graph, only the discoveries, or both overlaid.
