We know the m.o.m and the foretellers are vessels containing the 7 or 6 since ava wasn't there but what about maleficent we see in the past she was with a darkness and it was helping her quite a lot and she's already a being to uses a large amount and powerful amount of darkness it could stand to reason that she is a vessel for an eighth one as we know the remainder of the 13th darknesses are inside the data world but we do see one conversing with maleficent and luxu should already have a darkness unless he gains one in the data world and which case the same could happen to maleficent as when she talks with darkness that is happening way after luxu when she uses a lifeboat ive seen not many bring up this point as many still wonder why she's prevalent in the story and why she's basically still a main character after one this proves a huge point to where she stole very integral to the story despite not doing that much on the active control seat right now if this is indeed the case
