Can you recommend a novel about a mage and his Wind-type Holy Dragon mount?

The main character was a mage who had a Wind-Attribute Holy Dragon as his mount. At the beginning, he went out with the army to cast a light Forbidden Spell, something called Protection. He fell into a deep sleep for three years, and when he woke up, he went to snatch a bride. The bride seemed to be a noble lady. His mentor was a court mage. He knew some elven language. When he went out to travel, he went to the gathering place of the Wind-type Holy Dragon and became a Dragon Knight with his two companions. He also went to war with the demons and humans who had been silent for many years. When the protagonist was traveling, he met a demon. Moreover, his status was very high. He should be the crown prince of the demon race. And they had a deep friendship. The protagonist was not only a mage, but also a warrior and a priest. However, his level was not very high. He should be the only Forbidden Mage among the humans. Because he hadn't finished reading it, he could only remember this much.
