After a week of research I've found it. It took me an entire week and hours upon hours searching through these dusty old tomes, but I found the information I needed about her! I had the wrong name for that witch who stole my memories. She probably wanted to make sure I never found her again after what she did to me. "Shar," as if that's even a real name! She's a liar, and a thief. I only wish I would have known that from the beginning. From before... it no longer matters. That goddesses real name is Elaria Duskmantle. An elven goddess of darkness and deceit. A thief of memories. She promised me she would take away the pain and loss I felt from my old life.
I just didn't realize how she would take away the pain. She steals your memories! If you "serve her well", she gets rid of your awful memories. All of the ones that remind you of the monstrous things you have done before to yourself, others, and those you care about. In her service, she calls you to do such horrific things! Things that no one should ever have to hear about, let alone actually do! After you commit these atrocities, she removes the horrific memories and allows you to delude yourself into thinking that you have done some kind of good! She makes her followers believe they are The purest and holiest of clerics! I can't remember that time myself, but I have studied the way some of these tomes speak about her. As if she is the purest of all gods, with flowery language and bardic ode's to her benevolence!
No, I wanted out for some reason, I just can't remember what it was. She was displeased with me, that is for sure. When she takes the bad memories, apparently there is some cosmic filing box out there with your name on it, because she took those bad memories and shoved them all back into my skull for months! She left me an empty shell by removing my good memories, and then replaced them with a horrible memory, one by one. As soon as she saw how one memory broke me, she would give me the details of it until I was a sobbing mess. As soon as I would quit crying, or she thought I had found some peace, she would shove the next on back in and repeat the horrible description. I don't remember how long I was in her temple and at her mercy. It could have been years for all I know. I don't remember how I survived that, just that I did.
Well guess what you wretched elf succubus, I have found you again, and while I am not sure if I can kill you directly, I can find some way to remove your power. It will most likely not be anytime soon, but I will not let you keep using hurt people to commit your worst atrocities! I know who you are again, and I will find a way to remove you.
