Quest is given in some (non-Telvanni) city. Almalexia is a possibility if there's suitable ints/NPCs.
Cast of characters: One (1) Telvanni wizard who has moved away from Telvanni regions because he wasn't interested in the whole political powerplay thing and just wanted to be left alone with his research - basically a poorer, less high-ranking, less competent version of Baladas Demnevanni. He's working on teleportation magic.
One (1) neighbour (probably reasonably well-off) who is incredibly sick and tired of the explosions, screams and other weird noises at odd hours of the day, never to mention the odd charred thing falling through the chimney and the like.
Outline of quest: You get pointed in the wizard's direction by the neighbour, who wants you to make him LEAVE, peacefully if possible but if not... well, use your discretion!
Talking to the wizard, you find that he is already planning to leave once his experiments are completed but won't do so before then: basically, his teleporter prototype can't be moved. He knows the design is flawed and wants to start over somewhere else, but first he wants to wring every last bit of data out of it that he can. What he needs for this is a test subject for the last few runs. Slaves don't work, because it turns out that when you teleport slaves somewhere they just run off instead of coming back (he sounds faintly incredulous about this). Hey, you look like a healthy enough specimen...What he wants you to do is try out the teleporter and make your way back to him, and do this around four or five times. You must not use any teleportation magic in between using the teleporter and talking to him again, the explanation is slightly magic-technobabble but amounts to you ruining the data he wants to get. The evil variety of this would be actually disabling teleportation magic by script while this is going on (could be explained via him casting a spell on you for the purpose of data-gathering which has that as an intentional side-effect), the less-evil would be to just have a script running that updates the journal to "you failed the teleportation quest" as soon as you use teleportation magic. He swears this experiment is totally harmless, there is no risk, you'll just be teleported to the end of the street. Considering he also says things like "Nobody has exploded in over a week!" you might find this a little dubious.
If you agree: you get treated to a tour of Morrowind's greatest death traps. You are teleported to places along the lines of: out in the middle of nowhere surrounded by hungry durzogs, the depths of a Daedric shrine (possibly while a ritual is going on), the home of a necromancer, the middle of a large lava pool, an underwater grotto with no air bubbles whatsoever, (possibly) Red Mountain, (possibly) Solstheim in the middle of a group of werewolves, etc. At one point you get to do your best Tarhiel impression. The first place he sends you should maybe be barely survivable for a first level character (something along the lines of somewhere where they can't win the fight but can run away), but after that it gets steadily more lethal. Oh yeah, and all of them are absolutely miles away from this guy.
Also, since it'd be a bit unnatural for him to only send you to the northeastern part of the mainland, I imagine that at each stage it randomly chooses from multiple places of a similar level of lethality. This means that when there's a new release, one could just choose a few appropriate new places in the new areas and add them into the script.
Once you've limped your way back to the guy, you find that he doesn't care about the problems you ran into and just goes "What took you so long?" You probably have a choice of around eight different outraged responses to this, all of which he just brushes aside. He also doesn't give you a reward (you might have the option of asking, to which he'll just say something like 'the honour of participating in such ground-breaking research should be its own reward!') and just wants you to try it again.
If you go through with the whole thing: he moves out, as promised, leaving the finished prototype device behind. What this means is that you get a new fast travel option. It should be useful but not *too* useful, possibly sending you to five/six or so remote places scattered around Morrowind (no cities - rather than "Port Telvannis" it'd be something like "a cave in the Telvanni Isles"). No returns, there's no way to get back from the destinations. It might also have a small (2%?) chance of sending you to the wrong place or one of a preset list of random locations, albeit not ones as lethal as the places you ended up previously.
The neighbour gives you no reward, because they're so frustrated with how long you took. It's possible that they went and hired the Morag Tong, and are now angry that they're going to have to try and cancel that. (A way to vary the whole thing would be by having him attacked by the Tong at the very end and you get to choose whether to help him out or stand by and let them kill him/actually help them kill him. Alternately, have his corpse turn up somewhere with a writ lying on it after the end of the quest.)
If you kill him at any point: this is meant to be a very, very tempting option, and is a viable alternate path.
What happens depends on how many of the teleportation subquests you did before killing the guy. For each, the prototype is slightly more useful (1 extra destination, reduced chance of you ending up somewhere random, possibly the random places you end up being less dangerous), and the reward you get from the neighbour is less valuable/useful because you took longer. If you do none of the quests at all and kill him straight away, the prototype might be a "random teleportation" device, or might have only one destination with something like a 50% chance of that going awry, or might just not work at all. You also get something very nice from the neighbour. I'm not sure exactly what... this gets tricky because they shouldn't be too rich, but at the same time you should get *something* that, although not on the same level as a new fast travel option, isn't too many levels below it. Maybe a useful unique enchanted item (heirloom) or the like.
If we go with the less-evil variety, then teleporting during one of the subquests would mean that the wizard refuses to give you any more of them, the only way to finish this quest will be to kill him, and if you do your rewards are worse because the prototype will not count the failed quest (and hence be worse than if you'd succeeded at it), but the neighbour will (and hence give you worse stuff than if you'd never accepted it at all.)
Alternate quest start: It may be possible to start the teleportation quests just by talking to the wizard about his research. In that case, I'd need to work out what happens if you talk to the neighbour while you're doing these - if they still ask you to get rid of him or just view you as an accomplice and don't talk to you at all. Would definitely need to script things so that cool items from the neighbour/useful prototype are either/or.
