This is incorrect: they did not know about Priscilla nor were they told about her in the way you are implying.

At that point you linked, they sensed something Riful-like, and in this chapter, they sensed it surpassed the power of an Abyssal. Hence, another power beyond the level of Abyssal.
That is also incorrect. They sense Riful but could tell something was off. They did not state or imply that it "surpassed the power of an Abyssal" at all in that chapter. It may have been implied in the next, however. But Riful is clearly not passed Abyssal Level power. Priscilla is not breaking a sweat.
