[Dishonored series] You are Corvo on the ship heading to the south during the trip that proves unsuccessful. Assuming you cannot return to the isles sooner, can you influence events leading to the city receiving help? Can you disarm the conspiracy before it happens?

Do note that you don't have the Mark of the Outsider but you do know everything that will or can happen already.

Really there's only one thing you could do to change the events. That'd be to somehow buy out daud and the whalers to kill the conspirators before he goes after the empress. Everything else will cause a coup no matter what without enough evidence to undermine the various traitors publicly. Paying off daud to kill them first keeps jessamine in power without risking a schism in the upper echelons of society.
