No that's right Volk would be much too busy fighting itself, that's the natural state it's perpetually in, discord is its element. A house divided cannot stand, and all... Volk might have trained fighters and advanced technology but you cannot be a great army if that army is constantly destroying itself.
I also thought it was interesting that Lunatea was more modern, and Phantomile was more natural. Similarly, though Lunatea seems to have more advanced technology, Phantomile still has the natural elements on their side which could lead to a terrifying amount of strength.
