Kobolds in Wyrmsreise

Running an in-person campaign for the first time in what feels like forever and have been working on a setting for it for a while now. It’ll be using D&D 5e. Here’s some stuff on kobolds.

Hailing from the idyllic hilly grasslands of the First Coast, kobolds were the first species that the aboleths took under the wing, making the first moves to becoming the empire they have now. With a historied nomadic warrior tradition and a natural inclination towards cooperation and exploration, they were instrumental in setting the Mazzahim foundations. They’ve found themselves settled deeply as the backbone of the military caste and probably have the most flexibility in how they approach their caste, some reaching senior command and many retaining face while working soldier roles outside of the military.
 Kobolds are small statured bipedal furry mammals with muskelid-like features and seem supremely well-adapted to survive in most terrains and climates. Hard working, attentive, communicative, mission-oriented, and prolifically breeding, just a handful of kobolds can quickly turn into a civilization in any environment. This means even though kobolds were the rarest initial homesteaders by far on the Sixth Coast, with their offspring they have quickly become the most common by far. This doesn’t actually impact the geography of the region much however, as their well-hidden burrows blend in seamlessly with the landscape. They’ve so far proved themselves to be excellent neighbors.
 Although they can seem family-oriented, this impression often has incorrect assumptions. Kobolds are group- and mission-focused. With as numerous as their families can be, while individuals are shown affection, they’re soldiers. And very used to the grim realities of conflict.
