"Every one of us loses if Dagoth Ur comes to power."
Keep that in mind. I don't think there's a choice here.
Except that we know very little about this version's Dagoth Ur. If he/she's the incarnation of Princess Luna, that's going to throw things out of whack. If he's in league with Discord, that's going to throw things out of whack. If he's far more reasonable than some of our interpretations of him suggest, that's going to throw things out of whack.
Though personally, I don't think it's going to be a big deal in any case. We'll presumably have learned much more about him by the time we're in much of a position to be taking sides.
2. How do we know that they know each other? The only one who might be someone we know is the orc in daedric, and even then it's not certain.
Because they cheered her on, she went to them afterwards, and they left together? If there were five or six of them and none of them were the people we currently suspect to be ponies, that'd throw a wrench in the interpretation that they're the mane 6. Currently we have no reason to believe as much and a fair number of reasons to suspect otherwise.
3. Of course destruction won't become viable any time soon if we never train it! Why should we abandon it to grind weapons on mudcrabs when we've just got it? Why not just train magic on the mudrabs?
I think he meant we should train both - health AND magicka. So zap them, but let them beat us up a bit first, and fall back to weapons before time to sleep.
Spells don't work that way in vanilla Morrowind, and we've seen evidence to suggest that remains true here. Remember what Fast Eddie was doing when we met him? Remember what the guild guide said most other guides spent their money on? It's
casting the spell that grants experience. Whether you cast it on thin air or mudcrabs or Dagoth Ur himself should all be identical.
...This doesn't make sense in the context of Morrowind, since it'd require two PCs, but hey; there are other things that don't fit with Morrowind already:
What would require two PCs?
About that orc in Daedric armor. Who do we know of who's associated with the color green and would have a reason to follow around and protect someone who bears a certain similarity to Rarity?
...It's Spike, if I wasn't clear enough. The orc corresponds to Spike.
Fair suspicion. Awesomeicus fits the gender, though Rainbow Dash is certainly butch enough to roll a male character. He's less awesomeness-oriented than RB either, but I could see him being goofy enough for it.
Also, let's not get our jimmies rustled by not seeing the duel. We got a pretty darn eloquent description of it, which from our perspective is nearly the same as Michael actually seeing it.
I think hearing about it here would be the same as if we saw it?
We missed out on seeing Adorabella and her friends. That could have been
massive. The number of them alone had the potential to tell us a great deal, to say nothing of being able to actually see each one, in most cases probably without armor obscuring their faces.
Don't even get me started on if we'd managed to
talk to any of them about it, which I'll admit doesn't sound
too likely.
Go out into the swamps and become a master at destruction and all forms of combat by fighting mudcrabs for twenty years. Return to civilization and see what's changed.
But fo' reals, destruction and combat grinding time. Those mudcrabs aren't going to fight themselves.
Still gotta figure out where. I'd tentatively suggest warping back to Balmora, then meandering from there to Pelagiad, fighting anything we think we can take along the way (meaning rats, kwama foragers, and
maybe nix hounds) and fleeing to the nearest strong person for anything we can't (cliff racers, kagouti, alits). Also collecting alchemy reagents because why not.
Note that this is largely because I believe, but am not at all certain of, the notion that the things around Pelagiad tend to be fairly weak, that kagouti can spawn between there and Seyda Neen, and because I'm not familiar with the regions around Caldera at all.
Though actually,
can we take rats on our own? We might not have much choice but to warp to Balmora and Silt Strider to Seyda Neen for some crab and kwama bludgeoning if not. But then where would we sleep to recover?
