Door at Skyrest?? Spoilers

[FreshRevenge]

So after you beat Pieta, and head to the Skyrest bridge which will act as your nexus(Demon Souls). When you go down the spiral stairs and down and anotthe set up stairs there is a door that says "can't be open from this side" Does anyone know how to open it? Or how to get to the other side of the door.

You have to enter the Path of Devotion (the very first area you go after reaching Skyrest) and move all the way through it. In the farthest end, just past the cave with the vestige and the boss Sister Delyth (don't enter it) there are few ladders down. Then you have to go all the way back to the Skyrest via the lower path. That one is more tricky, with platform jumping etc. Eventually you will reach the mostly uninhabited and puzzled area. The key is there somewhere, you'll be able to open shortcut to the main base in a usual way.
