Some have fluff. Ramos in Prison, Nicodem dead. But a lot we don't know yet. From minor descriptions we can infer the Guild has had massive shakeups while the Ten Thunders have grown in power and influence while the Neverborn has seen older characters like Lilith imprisoned with her Sister taking her place.
