The Abraxion Witches live in a different universe from the one we are currently in. The Dark Lords have found a way to communicate with them, but as yet they have failed to open a time portal to bring them through. The Witches want to get hold of the AGLIA, but realise that it is only with the help of the Dark Lords of Dagger Bane that they will be able to posses it.
Once they have the AGLIA they will have no need for the Dark Lords, but for now they remain allies because without them, there will be no way to move out of their own time frame.
