The Vaporeon kingdom is called Waterguard, with a protection system of highly trained water animals (eg sharks, whales, dolphins) being used as mounts and combat helpers to Vaporeon warriors, who patrol the waters and ambush any invading human and co ships before they can get to the part of Waterguard on the seaside, and just before they can drop weapons to sink down onto the underwater segment of Waterguard.

Since I'm a little silly, I only have names for a few of the Eeveelution kingdoms, I'll list them here if you wish to include them, any other just make up to your likeness, I can't really stop you. Moonshine, Umbreon kingdom. Pollenbreeze, Leafeon kingdom. Glittersnow, Glaceon kingdom. Tarotsight, Espeon kingdom. otherwise that's all I got, mb lol

Some other specific details may be in the descriptions and such of the other anthro pokemon talkies I've made, so if you're unsure of something to specify and hope I'll have done it for you, go take a look to see if I've mentioned anything anywhere. (as you may have noticed I'm not very consistent hehe)
