The tale of the multiple monsters and the rat

During one of my countless missions, I was wandering in some dungeon in Daggerfall; with the "Levitate" spell I've got always active, I went up a hole to a room with some undeads in it (zombies or wraiths, I don't remember, actually the whole place was full of the foul things); after killing them, I opened the door just to find myself at a T-intersection, with a door on my right and a corridor on my left. I chose the latter and I soon noticed that it went down and immediately up again afterwards.

It turned out to be the wrong decision, as soon as I walked down the slope I started hearing the most horrible screams a living creature has ever heard: the unholy shouts of a Vampire, the cries of a Wraith, the frightening roar of a LICH... and even the squeak of a rat.

These omens should have  prevented me to go any further, but, you know, curiosity is too strong an impulse to be calmed down. I went up the other slope and I saw IT: it was like a living (well, to be precise, undead) column of creatures: the ones whose sounds I described before (even more than one for each type) with the tiny rat in front of them.

I was beginning to run away at once, when I noticed they stood still; well, in fact they were trying to step towards me at the same time, therefore hindering each other's movements, so the result was they could not move at all. Those foul undeads could do nothing but stare malevolently at me. I quickly realized that getting closer would not do any good to my health, so I slowly retreated keeping my eyes on them, fearing one (or even more) could free itself from that queer bonding. I staggered back to the room I came from and, still puzzled by the strange event, I paused a moment to think.

* Writer's Note: at this point I saved my game, then approached the creatures and tried to kill them all, but a couple of good blows of the Lich and the Vampire made me bite the dust, so I had to reload *

I went out of the room again, determined to go through the door on the right this time, when I noticed that I could not hear those chilling screams anymore. Only the feeble squeak of the rat remained. More puzzled than before, I turned left once again, walking down and up the slopes: as soon as the ferocious (hehehe...) rat saw me, it boldly (hehehe...) advanced, trying to bite me with its powerful (hehehe...) jaws; needless to say, I impaled it on my Dai-Katana with but a single, simple blow. And the other creatures? Where had they gone?

Well, the only answer I can give is "Who knows...?" To me, they simply disappeared; maybe some scholar could argue that a dimensional door to Oblivion opened and swallowed them all, but the only thing I thought was that I was just relieved not to have them in my way anymore. I encountered those "multiple monsters" other times, but, unfortunately, they didn't disappear anymore, so I simply avoided them.

(* Writer's Note: I tried to save and reload, but nothing happened *)

Only once I found a bunch of Thieves and Burglars (and maybe some Nightblades too) altogether in this strange position, so I took the chance to kill them all and, oh, what a treasure I found: thousands of gold coins and dozens of weapons and armor parts. My bank account turned out well replenished after that encounter...
