Sen's Fortress - p. 3 | Walkthrough Dark Souls Guide

Switch the machine, so the rock will fall to a corridor where you were previously.
A rock will hit a sleeping lizard and break a wall behind him.
Inside you'll find two closed cages - in one of them NPC Big Hat Logan is kept. Open the cage using Master Key or Cage Key (this key can be found later in this location).
Once again return to the chamber, where balls are loaded. This time use a small side corridor (where rocks can't roll). Watch out for a trap - there is a button in the middle of the passage. Run quickly over it and jump to the side.
Behind the trap, turn left and walk until you get to another swinging blades. This time you have to run past them all at once. Prepare to do it when blades start swinging from a central position to sides.
On the other side deal with a lizard to the right.
In the opposite wing of this level you'll reach a stairs up - at its top a mage is waiting. Lure him out and kill him. Before you go up, explore the bottom part of the corridor. You'll find another monster guarding items.
On the upper level you'll find another trap with swinging blades. But before you go through it, kill a mage to the left, using the bow. Lean out from behind the wall, shoot once or twice and then hide again to avoid his lightning attacks.
Once you eliminate him, move slowly to swinging blades. This is most difficult moment, but it can be solved very easily. Stand in front of first pair of blades and wait until they unfold. Then quickly jump forwards and stop in front of next pair of blades. Continue this until you get to the other side.
When you get to the stairs, watch out for two stone plates in the floor - they activate a trap.
Go up the stairs and enter fog.
You'll go out - from this place you can choose two paths. First, go down the stairs.
You'll encounter a knight - you were fighting with similar monsters in Undead Parish.
Go to the bottom and kill another knight, guarding a chest. Inside you'll find Flame Stoneplate Ring, which will be useful after a moment.
Go back up and go up the next stairs. [1] Stop in the middle - a flaming bomb will be thrown at its top. So use now the Flame Stoneplate Ring. [2]
Wait until fire from one of the bombs goes out and then quickly run to the stairs on other side - stop under the wall there.
