He spoke to it in parseltongue for a short while, and to Mimir's amazement, the green twin-horned dragon lowered its neck to allow the Lord to clamber on its neck. Mimir had seen this many times, but it still seemed incomprehensible to him that the Lord could whisper a few words in his snake language and control the dragons so deftly. The dragon shot a look at Mimir, and the giant stepped several paces back to allow the dragon room to expand her wings. She flapped them once, and Mimir felt a gust of air. Another time, the two were lifted off the ground, and before Mimir could blink, they had flown away high into the sky, soaring above the mountain. Albus felt the thrill of the flight and power of the full-grown dragon below him. Riding a kestrel was one thing, but riding a dragon was something else entirely. They glided at unfathomable speeds around mountain peaks, ducked under clouds, and soared amongst other dragons who paid Albus little heed as the two flew around them. They landed back miles away from where they had embarked but still somewhere in the city of Delphinor.  Albus stroked the neck of the green dragon before she flew off again, no doubt to explore the forest for food. He could till apparate, so he appeared instantly by Mimir's side, who jumped up in shock. The giants were unused to magic and were generally suspicious of it, but they permitted Albus to use magic when he visited. Such was his esteem amongst them.
