So, the threat ranks are:
[ul][li]Calamity[/li]
[li]Great Disaster Disaster War Man-Made[/li]
[li]Disaster[/li]
[li]Harmful[/li]
[li]Harmless[/li][/ul]
Though, on a more serious note: that is a really weird ranking system, going from "Harmful" to "Disaster"
I mean, a normal wolf could be harmful to a child, or to the livelihood of a farmer if it targets livestock, and a pack could be harmful to a single person, but would a boar be considered a disaster since a single boar could potentially be harmful to a small group of adults, while a single wolf would be harmless to the same group?
And putting aside the spacing issues, why is "Man-made" its own rank? That doesn't really specify how dangerous something is, just the origin.
I mean, a group of bandits would technically be man-made, but if someone created a bunch of golems made of stone and sent them out to kill people, that'd be significantly more dangerous, but still be man-made.
And is it "disaster war", or is disaster the name of two different ranks (not counting great disaster)?
