Don't do anything.
Scan the landscape for that pole you broke off. If you can't find it, forget ok give the next update to someone else.
If you can find it, ask Richard if he can make something of use, such as a crowbar or something.

Before you walk to find it, a crowd of blood muks starts walking slowly towards the small white pedestal in the ground below the flying island.
Jacob: Where are they going?
Richard: I have no idea, but it can't be good.
Richard: The witch is probably summoning them or something.
Richard: You should go follow them, maybe you can find an entrance to the castle or something.
Richard: I don't know how I can assist you anymore, so you haven't much choice left but to go there.
Wat now?
