That is something I could see happening.

She hasn't taught me any dark magic, though. Says it's too dangerous

Dark Magic is far to much for some people. But it can corrupt ones heart also.

Is it because I'm part-Succubus or part-Angel??

No one can truly tell for you.

I take it she doesn't want to risk it. Same with my sister

That could be it.

Come to think of it, Lorelei never taught me transformation magic, either

That takes much time and effort it also needs a un wighted mind to do much of it.

Oh, it's because she's a ghost that she could do it!!

I didn't think being a ghost would have much to do with it.

True. She could do it before then, too

It a self discipline thing, I'm sure of it.

Do you think it would be possible if I want back in time to see for myself??

It could be or not but it is never really wise to go back.

I've done it before. But only 50 years or so. And I've been to 20 years from now several times
