As Delilah didn't (canonically) die in the DLCs... she was trapped in the Void. Obviously, her power has grown, and she probably absorbed some of the properties (and essence) of the Void increasing her magic, power levels, and (as see in the trailer) the inability to be slain easily.

She survived such an influx probably by being bound with that tree, and was able to, over the span of the fifteen years of her banishment, slowly integrate such power with no ill-effects.

Her coven, however, was still linked to her and also could have gone through similar changes - basically being changed, warped, and corrupted by the essence of the Void. Unfortunately, these women had neither the Mark, no a binding agent (such as the tree) and may have been directly affected by the power of the Void resulting in their bodies warping and their blood becoming this ichor substance.

They may also have entirely lost their sense of self and become mere shadows and/or puppets of their dread mistress as others alluded, and be nothing more than obedient shells.
