How do you do the first gate because I have 2 find some stone to close..

Well, I beat the main quest so it's easy to me... First when you enter the gate go left of the bridge and keep going til you get to the lake of lava. Then, turn right and follow twell, I beat the main quest so it's easy to me... First when you enter the gate go left of the bridge and keep going til you get to the lake of lava. Then, turn right and follow the path all the way (watch out for falling boulders). Next, take the first right turn. It should be right after you turn. Right away take a left then go left again then right. On your left there should be a door that says "portal to the bloodfeat". Enter it. Either door in this room works. They both go to the same place. Make sure it says "door to the rending halls". Next, head up the ramp and again, take either door. The door should say "door to the corridors of dark salvation". This room has a few traps but if you see holes in the walls you can avoid them. If you see a dead scamp, it means that it got hit with a spike. Follow the bridge and you should end up at a door that says "door to the reapers spawn". Enter it and go up the ramp. Kill the keeper dremora and take the sigil key. Go back to the corridors of dark salvation and use the sigil key on the first door to your left. Follow the path and take the first door on your right. The door should say "door to the sigillium sanguis". From here on out, you should be able to figure it out. Once you finish one oblivion gate the rest are easy (took me a week to beat my first one). The stone you were talking about is called the sigil stone. If you need more help just leave questions. Ill be more then happy to answer them if I see them.he path all the way (watch out for falling boulders). Next, take the first right turn. It should be right after you turn.

Cheers to the dude above, but there is a simpler way to explain it:

Just look for the biggest tower. It is usually in between 2-3 other towers, with catwalks between them. Go into the this tower, and basically just head up up up, until you get to the Sigillum Sanguis, then take the stone. BE CAREFUL!! Dont go too close to the stone or youll hit the fire beam and get absolutely iced....er, toasted. Heh heh
