Kobolds

Kobolds in most D&D settings are the trap-laying little son-of-a-guns who like to hang around dragon lairs. That's more-or-less true for the kobolds in the Call of the West campaign setting, only they take it a little farther-- not only hanging around dragons, not only worshiping them, but worshiping and being beholden to a specific dragon. When that dragon dies, whether of natural causes or adventurer-related injuries, the kobolds stay in the dragon's lair, preserving its bones, celebrating its life and deeds in festivals and rituals, revering it for generations.
