So let's get weird with it for a second.
We put out the Aug pretty recently but this one has been in playtest for a while (almost since Starfinder came out). We just released the Dragoon (or "Mewthian Dragoon", formally). We really dug the way the Solarian got into the lord of the universe so the Dragoon did too.
Short Version: You are a quasi-immortal soldier bound to a set of haunted armor by a dragon god.
The Mewthian Dragoons are the result of a tragic war on a graveyard planet reserved for the most ancient of space dragons. Those servants of the great wurms who died were resurrected to continue the fight when their dragon died. Now they are legion- organized into sacred orders and dispatched across the galaxy to combat evil wherever it rears its head!
There are now orders who are not from these original one; it was kind of the inciting incident. Now secret societies, wannabes, heroes, religions, and even people who can just afford to buy their way in can join orders (or make one if they have a dragon buddy). It’s not really tied to a setting (or even the lore- there is a section discussing how to do it in a setting neutral way).
We spent a while playtesting it and even ended up doing a high level (18th) playtest (Starfinder get pretty chaotic at 18th) one. We had a bunch of playtesters and used a bunch of different orders (they all play pretty differently).
In combat they are definitely combatants; the same ilk as the soldier and solarion. It tends to be easier to target EAC with them and they are not “elemented” but tend to favor one element (though there are some orders with odd “elements”, like “euphoria”).
We really hope you guys give it a read and play with it. There is a lot more depth just under the surface. The art was done by Naiche Washburn and Rui Ferreira (I mean... look at that cover!) and I know you are going to say that it was worth the few bucks you spend on it.
You can check it out on DriveThruRPG and our Patreon.
It’ll be up on Paizo in a day or so and we will update the thread with a link there when it is ready!
