I've just started reading The Final Empire by Brandon Sanderson and I think I have some misunderstandings about Kelsier's plan.
At the first meeting of the crew in Camon's safehouse Kelsier says:
"But if we play this right, we might be able to force the Lord Ruler to send the palace guard - maybe even the Inquisitors - into the city to restore order. That will leave the palace itself exposed, giving Yeden a perfect opportunity to strike."
As the palace is located inside of the city, how can Yeden go in if the Inquisitors and the palace guard will be in the city? Please give no spoilers for events which come in the book after this meeting.
