I'd assume so. I can't think of anyone else with that kind of power.

[She's dead now but she was alive once in either a place or a time far removed from this one. Or it's all lies and they brought her into being in this place. Either way, they must be extremely powerful to hold such power over life and death.]

It is strange that they should remember and we don't. It doesn't make much sense.

[The past isn't something she wants to think about, not at all, but it is odd that some brought here would remember while others don't. What possible purpose could that serve?]
