Thanks for the feedback! 
Here is a list of have some more ideas/ changes for the race:

-I agree, Germina sounds like a good name and I plan to use that from now one! :D

-Ironically, for some reason, the Germina are usually unable to even use Herba magic. Germina seem to have a strong affinity for Venunum along with Lux and Terra. Since poison is one of the easiest ways to destroy the seeds, practice of Venunum is outlawed. Aside from Herba, Germinas are typically unable to express any sort of proficiency in Gelum, Machina, Metallum, and Permutatio. 

-Magic use in general is greatly frowned upon by the Germani. In fact, many have been banished because of them being suspected of unauthorized use of magic. A separate permit is required to practice each of the affinities within the kingdom. Here is a list of forbidden magics (aside from page five of the affinity list):
	-Cognito (Dangerous magic to play around with)
	-Fractus (Seeds explode... bound not to end well...)
	-Venenum
	-Viniculum (There are all sorts of nasty ways seed people can be burried alive, suffocating to death over and over with this)
	-Tenebris (2 spooky 4 me)
	-Ignus (Because fire is a great way to destroy a seed)

-They remain isolated through a mixture of the location of the Kingdom and their distrust and aggression towards strangers. Since the area is not particularly rich in materials and hard to reach, many don't find it worth the trouble of setting up any sort of trade agreement or attacking it for use of the land or any particular materials. Despite their ferocious fighting ability, they don't like getting mixed into wars.(More people tend to have heard of them then I have previously stated, so secrecy plays a much smaller role in their isolation.)

-Their faction is known as the Brotherhood of the Germina or the Germina Kingdom to many outsiders. (As opposed to the Germina Nation, which I still like, just not as much as Brotherhood.)

-Perhaps Sacert is an enemy of the Germina that used to raid crops from them and the women befriends it? That would be interesting...

As a side note, I have an idea for a character that I'll probably post soon.
