[TIPS] Skyrim: Getting past the final door/gate in Serpent's Bluff Redoubt

The last door in the Redoubt (where you kill the Hargraven) is only opened by a pressure plate.

The plate is in the same room, on the table below the gate.  Grab an object (hold the "search" button, which is the E key on the PC) and drag it onto the plate.  A corpse will do nicely.  That will hold the door open.
