There is a broken down fort that is the base for some weak vampires directly south of Chorrol. The fort is called Fort Carmala and is located near Hackdirt, very close to northeast of Weatherleah. To reach it, if you have not done the Hackdirt or Weatherleah quests, go to Chorrol. Leave from the south gate and move directly south. If you reach the city of Hackdirt, you are close to it. Look for a group of white rocky ruins. The door to the cave is among the ruins.
If you load a save file in which your character is a vampire, there is a chance that your character's facial features may revert to the default facial features for that race. If that happens, try loading a previous save file. However, it could be permanent. Always try to keep a file that was saved before your character became a vampire.
