Dragonoid beast

"In the temperate swamps are small tribes of dragonoids that would appear to be oversized northern dragonoids. However these groups actually consist of dragonoids who have succumbed to the dragon fever years ago and have become feral. Overtime they have become marginally more civilized, meaning that they don't purely attack everyone on sight. A rare few northern and southern dragonoid know the locations of their dens and do some occasional trading with them, trading rudimentary tools and food for equipment they have 'found'."
