Silver fangs are indicators of rank and combat proficiency within the Iron Fang Convoy.
Quote
Each member is required to wear a sort of keychain with a number of fangs, going from 1 to 5 depending on your combat proficiency.
The number of fangs indicates rank:
- 1 is the starting rank.
- 5 is the highest rank before receiving specialized titles like Canine, Molar, or Incisor.
- Members are required to wear them visibly to indicate their standing and as a warning to potential troublemakers.
