What now truly was the questions.
After an hour of conversation you and Enven come to a agreement. Being a white Mage, he was also a bit of a researcher and at any opportunity would always try to analyze demonic magic and its weaknesses. However, capturing a live demon was as easy as trying to find a coin at the bottom of the ocean. Especially since a captured demon would try to commit suicide after being captured.
In return for you being able to stay at Enven's temple along with being given food and water, (though Enven did have to stand next to you when you used the bathroom to ensure your little snake wouldn't come alive) Enven would be allowed to perform experiments on you. Nothing cruel or crazy, merely taking samples of your blood or seeing your reaction to a minor amount of divine magic.
However there was another benefit. Your not sure why Enven got the idea in the first place, nor why you even accepted it, but he had also agreed to teach you the basics of magic; the art of nature magic.
It was a grueling experience, ever day you spent eight hours a day practicing, reading, and experimenting. At the end of each day, after being taught by Enven you would nearly collapse onto your soft bed. You learned how to control plants, make them shrink or grow, how to make a simple flower turn into a tree or how to make a leaf as hard as steel.
As the lessons went on you began feeling incredibly tired. The magic of nature did not mix well with your demonic body so you found it much more draining use nature magic than the regular human would. You even went into a coma a couple of times and would have to be nursed back to consciousness by Enven since healing magic doesn't agree with you either.
You felt grateful to Enven for letting you stay with him, however there were moments that made you suspect Enven. In the middle of the night, your sharp ears could hear Enven quietly stand outside the door to your bedroom. He would never come in, nor would he move for hours, only your ears could hear his faint breathing as he stood.
Not only that, Enven also seemed to go out on journeys to neighboring towns, saying that as a White Mage he would usually go out and deal with magical issues any nearby settlements would have. That itself was not very suspicious, you've noticed him write letters, and at the corner of your eye you could see your name being mentioned. You never asked Enven about it, mostly out of respect and fear that he would be angry at your questionings, despite Enven never snapping at you or getting angry at you at all. Perhaps his divine magic put you off a bit?
Though it may have to do with your secret that you've kept from Enven. When you slept you rarly had good dreams. You had strange ones. Most of them were you standing in a empty pitch black room. Strange voices would whisper and and laugh inside your mind. They spoke in a strange language that you never heard of before but somehow understood it as if you were born to that language.
They spoke to you of magic. Demonic blood magic. You tried to ignore their ramblings but when you did, they grew louder and louder until you had no choice but to listen.
In your room at night, you would slightly cut yourself, nothing dramatic, only to draw blood and when you practiced using the knowledge the voices gave you, you found that it was much more easier than using nature magic. To the point where it seemed as simple as lifting a finger!
You could make your blood hover and move in the air or turn it into a sharp red metal blade that you could control in midair. It was fascinating. It was scary at the same time however. Your lessons from Enven told you this was dark magic. Something that should never be used. You knew that if Enven's found out, he could possibly kill you for practicing such dark energy. Yet there you were playing with it, watching the crimson liquid flow gracefully through the air at your command.
And this continued for about seven months. Then you had to leave the shelter of Enven's temple forever.
