As it sounds like, I've been setting up some xenophobic Merfolk for my campaign and after some tinkering realised the merfolk-cavalier-enabling and order parts actually split pretty neatly. Still, I'd appreciate some opinions. The 15th level stuff isn't going to come up, but I'm aware its probably potentially a bit strong.
The Archetype is designed for a city intended for both Merfolk and surface-dwellers alike, with waist high-waterways everywhere and rings of water-walking everywhere. These Cavaliers would be the lightning-fast response team and police, using the environment against any outsider infiltrators.
