Here at Freedom City Play by Post, it can very difficult to come up with a possible threat to challenge your newly made character. Well, this site has been around for some time which means there are many NPCs just waiting to be used in a thread. There are three levels for NPCs which dictate how they should be used.
Tier 1: Open for anyone to use. Tier 2: Can be used only with permission of the NPC's creator, and the creator has the right to request that they be the one to actually run the NPC. (Most archnemeses should fall into this category.) Tier 3: Reserved for Ref use only.
