To gain access to Pashid, you have to destroy either the Right Gate of Gateway, Left Gate of Gateway, or Loose Wall. You can also destroy the Main Portcullis, but then you'll have to deal with the Rear Portcullis.

If you enter the Siege Base, you'll see a Reserve Trebuchet. Use it to destroy a gate or a wall. If you capture the base, we'll send you the fuel and cannonballs for the turrets you need.

When you're done, we'll meet up at Beritra's Bane Encampment.

Player: Accept.

I've been waiting for you.

Were you able to gain access to the fortress?

Player: "Yes."

Well done! Good job.
