If the dragon approaches a hunter and tells him to deliver a message than most likely the whole town will know about that dragon. Influencing the politics of that town is impossible than as everyone will be on the guard. Also to be really into politics the dragon needs regular contact with the people he influences.
And those dragons who don't are those whho only sit in their cave doing nothing until teh adventurers come and slay them. The only thing they can do is maybe to threaten some small villages and raid caravans. But that are heroic tier adventures suitable for level 1-10 adventurers. So either the dragon is just a low level monster or the dragon does not function properly.
Gerric the hunter gaped at the monstrous Wrym in front of him. Until now he had believed them only to be legend.
"BE STILL HUMAN, DO AS I COMMAND AND I WILL NOT HARM YOU"
It's giant red scales bristled as its voice echoed through the clearing. Gerric felt his guts tighten, his legs buckled and he fell to his knees. His hatchet fell from shaking fingers.
"ARE YOU FROM THE SETTLEMENT YONDER", its head nodded to the west.
"Y-yess, it is called Taskia"
"TELL ME ABOUT YOUR TASKIA".
The Dragon interrogated Gerric for several hours and learned all he knew about the small town of his birth. Finally he sent Gerric to the mayor of the town with a message demanding he come to the clearing in ten days hence or the town will be destroyed.
Gerric went straight to the major, fearing the panic it would cause he told noone else of the dragon.
The mayor met the Dragon, with only the fearless captain of the guard for company, agreed to pay the Dragon tribute of cattle and treasure in the clearing every month. The Dragon added another town to his growing list of conquests.
The dragon offered his protection to the town and would defend it against other Dragons or large threats. Over time the Dragon, through guile, befriended some of the humans entrusted with the delivery of his tribute. He begin to learn more of the secrets of Taskia and using his agents, supreme intellect and long attention span, manipulated the growing town.
The tribute to the Dragon became a dark secret in Taskia, until one day , blah blah....
