When Ondra speaks about Eyeless, she says that she "reprogrammed" them to fit her purpose, and that they are a perfect tool because they are mindless, relentless and obedient. From what I understood, they mindlessness is important because they don't remember what they do and destroy, so when they bury a secret, the secret stays buried. However, when you talk to them after destroying the crystal, they are obviously a thinking entity with the ability to remember things(although not remembering what happened between Abydon's death and the destruction of crystal). Is it some kind of internal inconsistency for the sake of narrative, or have I misunderstood something?
