Don't go alone. (not so classic anthro red dragon)

You may not be as big and strong as most red dragons but you are among the smartest of them and that's helped you survive quite well so far. Instead if razing villages, maidens and hunting food you've made some arrangements. Those arrangements include a trade deal with the Merfolk where they bring you materials and you give them some of the things you forge with those materials. You've also managed to sign non-aggression treaties with a few Elven cities (that took a lot of work, including a few duels) and you've been friend with the leader of an orc clan for multiple of their generations now. One of their best warriors is joining you now to fight the 'hero' who so rudely interrupts your slumber.

The knight stops in his tracks and hesitates a little before charging at you like the boar he probably is. You suppose the sight of a seven feet tall bipedal red dragon clad in black armor carrying an eight feet long spear, flanked by a six feet tall female orc in the same armor carrying a war-hammer as big as she is might be a tad intimidating to a human no matter how well he is trained and armored. Your good friend Lavender sidesteps the charging knight as you fly over him with a single flap of your wings. She then smacks him off balance by hitting the side of his shield with her hammer and stuns him by bashing the pommel against his helmet. You take advantage of this by stabbing your spear into a weak part of his armor at the lower back of his neck. When you pull back he falls to his knees and grasps for his throat only for Lavender to hit him square in the face, and with her fist clad in steel that's enough to knock him .
