[okay Matt can be forgiven for not uh. looking up at the lake. Cao Pi's tone is dead serious]

It's gone. Entirely. The entire bluff appears to have been washed away.

There is only so much we can discern from a distance in the darkness but the light is gone and the black shapes of the bluff have changed. Now that we have some starlight to see by, we can see that much. But without having someone who can go there to see it up close, there is no way to know if the Keeper survived, or if any of it is salvageable.
