# Name

* Unique and can consist of any combination of uppercase letters A-Z
* Between 13-26 characters long at launch (will change across Seasons)
* Can contain a "spacer" (bullet) for readability, e.g. UNCOMMON•GOODS
* Uniqueness is independent of spacers
* Spacers can only be between two letters and don't count toward the character limit
