A dryad

Your faction had received information about a gathering of druids. They all belonged to the enemy faction and there was little doubt it would spell little good for the war effort.

So you were sent in. Dressed like a fellow druid, you snuck into the grove and discovered what the druids were up to. They were about to awaken an ancient tree as a treant. A humanoid version of said tree, that was able to walk and fight. Treants were very powerful creatures so there was little doubt you had to stop this ritual from completing.

That was when you saw her. A beautiful woman with hair like leaves and light green skin. There was only one kind of women like that in the world and that were dryads. Ancient creature of the forest devoted to life and nature.

With you being a practitioner of **** magic, she was the complete opposite of you. You considered how wonderful it would be for you to have her. Or better yet, corrupt her to join you in the glorification of ****.

You revealed your true self and released your magic. Druids died left and right, and before the survivors knew what was going on, those that had died were already walking again. This time as zombies.

The dryad put up a little struggle, but you managed to capture her and take her to your castle.

This castle was a true fortress of ****. It was actually a large mausoleum. Whenever people in the country died, there were entombed here. There they would remain until you decided they were ready to be revived.

Some people would come before they died and would request to be turned into a vampire. Sometimes you agreed to this, after which they would spend the rest of eternity in this mausoleum.

You decided to trap the dryad on the roof. Since she was a creature of nature, she would require fresh air and sunlight to stay healthy. It has been a few days since you returned and were getting curious about her.
