+### Workflow 10: Write an English Novel
+
+```bash
+# Create an English LitRPG novel (language auto-detected from genre)
+inkos book create --title "The Last Delver" --genre litrpg --chapter-words 3000
+
+# Or set language explicitly
+inkos book create --title "My Novel" --genre other --lang en
+
+# Set English as default for all projects
+inkos config set-global --lang en
+```
+- 10 English genres: litrpg, progression, isekai, cultivation, system-apocalypse, dungeon-core, romantasy, sci-fi, tower-climber, cozy
+- Each genre has dedicated pacing rules, fatigue word lists (e.g., "delve", "tapestry", "testament"), and audit dimensions
+- Use `inkos genre list` to see all available genres
+
+### Workflow 11: Fan Fiction
+
+```bash
+# Create a fanfic from source material
+inkos fanfic init --title "My Fanfic" --from source-novel.txt --mode canon
+
+# Modes: canon (faithful), au (alternate universe), ooc (out of character), cp (ship-focused)
+inkos fanfic init --title "What If" --from source.txt --mode au --genre other
+```
+- Imports and analyzes source material automatically
+- Fanfic-specific audit dimensions and information boundary controls
+- Ensures new content stays consistent with source canon (or deliberately diverges in au/ooc modes)
