Books 1-3 were originally 1 book and was an homage to Tolkien and LOTR. So far as I understood, as 1 book is was far too large for publication and it was broken up into 2 and then finally 3 books. Book 4 is when RJ really starts getting away from the LOTR chasing/being chased meta and begins really building on his cultures, world and begins to tighten/tidy up his magic system. There's a lot of things in books 1-3 that we later began calling early bookisms due to them not really following the rules established further into the series.

Unless we see Rahvin playing an instrument, It has to be Asmodean doesn't it? We'll see I guess. So on another note, I was obviously wrong thinking they merged Lanfear and Semirhage. So that said, if Lanfear has been more cruel and brutal than she was in the books, how far do they have to go with Semirhage now? That's kinda scary to think about.

So we have 5 confirmed Ishamael Lanfear Moghedien Sammael Graendal ??? ??? I think we all agree the figurine with the musical instrument is Asmo leaving only one more. I don't think we're getting Demandred, I think they're merging him with Sammy especially after the info in spoiler above. I also don't think we're getting Semirhage as I think she has already been merged with Lanfear. Lanfear in the show is far more cruel. kills indiscriminately and even enjoys it. This is far more in line with Semirhage. Lanfear in the books rarely killed except during fits of anger as she pretty much thought it was beneath her almost like killing someone with her own hand would acknowledge they were a threat to her or her equal and no one was her equal. So who does this leave us with? Mesaana Aginor Balthamel Be'lal If that one figurine is indeed a 4th female, it's obviously Mesaana or I'm wrong about the Lanfear/Semirhage merge. Or That figurine is actually a male in fancy clothes, is Rahvin and they aren't merging Sammael and Demandred. Thoughts?
