Justice is a fan-made global mod.

It would be better to use the term "chaplain" instead of "preacher" - chaplains were military priests.

I liked it. It fits:smile01:

Raider griffons, assault griffons, battle griffons, imperial griffons...

1) 2) Doesn't fit, as they are more of a defensive grade.
3) The wording "battle" is quite strange, considering that all creatures are combat units because they all participate in battles. Here, it might only be suitable for mages.
5) It's okay. However, both grades can be considered imperial, as they are both used by the empire. There seems to be some confusion. For some reason, the empire has a king and queen, not an emperor and empress, and the griffons are royal. But it can be assumed that Saint Isabelle changed everything to imperial.
