In some games, Dragons are powerful setting defining creatures.π They shape entire regions, soaking with terror every soul within reach. Something as notorious as a kaiju flying lizard that can turn to ash entire cities takes a lot of attention. Followers and remora wanting to live off of that power will sprout, it's just a matter of time.
1. An arctic city is heated by the underground sleeping dragon. In return, the peasantry makes sure slumbering music and aromatic candles keep the fat lizard asleep.
2. Cultists drink this dragon's blood to go berserk. Has to be done through the dragon's eye (only spot without scales). Of course, this dragon loves the flattery of worship.
3. Yaach are hairy bison-like creatures, their pelts reaching the ground mutating its coloration to blend into their environment, making them very hard to spot. Their huge trunks are used to drink and eat (mice, oversized insects). They are mammals, but wish otherwise. Will hatch a dragon's egg for as long as needed, given their protective instincts.
4. The dragon lives in its tower, overseeing and protecting the duchy with a menacing gaze towards external threats. The fierce rule of Law reigns here! Every seventh year Tribute hits, and the dragon takes a maiden as payment for its services.
5. A Red Dragon is flying over a Pickle the size of a galley, impaled on top of the Cathedral's spire. Every so often, the dragon dives into the cucumber and takes a lick, doing so makes it regain d6 HP and go into an elated stupor. (See here)
6. This Black Dragon is at the center of the Ghoul oligarchy. Improvised sage, counselor, confidant. There is mutual respect and understanding, but utter dependency. See, an addict, the Dragon depends on the oligarchs to provide the drug it needs to feign death.
7. Gets teeth pulled to be used as magical daggers, by mousefolk and wererats. Gets trinkets and candy in return, perpetuating this arrangement. This, in turn, evolved into a children's tale.
8. Selling its offspring, the eggs land on a powerful but wealthy wizard. The magician likes them scrambled with salt & cheese. He gives spells and rare books for the dragon's lain eggs in exchange, and as a dragon's hoard is the most important...
9. The Pink Fog and Mist of the Yahaleh Steppes is magical in form and nature. Source of a 1000 gruesome tales, feared by merchants and travelers, it gets avoided if possible. An ancient dragon, however, has taken residence within in the last year. Breathing the fumes for that amount of time makes it (as if by a Geas) incapable of telling the truth. On the flip side, the Pink Fog caused Sapphire Gems to grow on the barren land like tubers, which the wyrm gladly harvests.
10. Actually this dragon is the "little sister" in this relationship. Serving as the furnace of a kingdom of fire giants underground, underneath a mountain complex. Outraged by the working conditions and wage, it is planning an uprising.
π Some people take offense at only seeing dragons in the mid- to high levels of play. "But it's on the bloody title!". This is a known (perceived) problem since 1974. And of course there are a lot of ways to have them present in the game from level 1 on. I personally have thrown a lot less dragons at my players than I should have, and for that, I repent.
