As soon as I arrived on the other side of the Great Gate, I saw another, huge, iron gate in front of me. A moment later, bolts fell with a loud crack, and great hinges groaned in agony as the huge doors slowly opened before me.

In the distance, I could see at least four towers guarding a fifth tower in the distance. The heat from the pools of lava made it almost impossible to see, but something near the fifth tower was spinning, almost like it was...walking.

It was walking! This was the siege engine that Martin had warned me about. Like a huge insect, one set of legs pulled forward, then another segment, and yet another.

And I only had 15 minutes to find the Great Sigil Stone to stop it.

I counted only two daedroth before me. I took a healing potion, then ran like a madman at them.

I took out the one on my left first, then the one on the right.

The towers were situated so that the four towers straddled the lava pit that the siege engine was walking through. The rocks were too high to climb. If I had tried, I would fall into the lava pit below. All the healing potions wouldn't be enough to save me from that. I looked up, noticing that all the towers had corresponding bridges between them. I just had to find which one lead to a successful crossing to the fifth tower.

I went into one of the towers, fighting my way up the spiral walkway to the upper level. There were guard creatures, but nothing significant. All were meant to delay me from getting to the main tower.

I turned and ran back on the bridge to the first tower, headed down, and out a back door.

I found myself being shot at by fireball towers. I stood behind a broken support structure, as the huge siege engine slowly stomped its way past me, like a huge worm. I had no spell capable of disabling it.

I ran to the end of the walkway, only to find that it was broken off. Below, lava. A few feet away, solid walkway. I put up my broadsword, took a deep breath, and ran as fast as I could, leaping into the air, and landing on just enough solid ground to keep from falling backwards to my death.

Another tower lay in front of me, and nearby, a huge iron gate.

I had seen these before. I ran into the nearby tower, slaying anything that moved. I made my way to the top of the tower, slaying the two Dremora guards there. As expected, there was a huge handle operating a release mechanism. I pulled the handle, resulting in a deafing clatter as the gears pulled at each other.

I ran back to the bottom of the tower. As expected, the huge iron doors blocking me from the fifth tower were now open.

But I was running out of time....

My journey to the door of the fifth tower was blocked by a Dremora Valkynaz, and he was pretty pissed off at my being there.

I took too healing potions, along with one to increase my strength, and ran right into him, knocking him to the ground.

"Get up." I shouted. I wanted to give him some payback for my home of Ald'Ruhn.

He obliged me, getting up and swinging at me with his weapon. I spun around, hitting so hard he fell backwards, right off the walkway. The last thing I heard from him was a scream of agony as he hit the lava pit below.

The doorway to the fifth tower was now open. I ran up the stairs, slamming the doors open, summoning five creatures at once, and let them clear the way for me.

All the while, the siege engine continued its relentless walk towards the Great Gate.
