The other necromancers may be inclined more toward domination rather than experimentation. The Pirate King didn't even use his powers until recently, and Nightroars is apparently as cliche as an evil insane necromancer can get. While neither of those traits necessarily mean that they don't experiment with their powers, it also doesn't show that they're aware that necromancy involves anything more than raising the dead. They certainly haven't gotten any farther with golems than we have; otherwise, we would've heard reports of random household objects marching alongside the dead.
If I metagame a bit, I could also say that it's a terrible idea in general to give every power we discover ourselves to our enemies as well. That would cheapen the whole deal, and in this specific case it would also be quite unrealistic- the Jeweled Coasts aren't exactly famous for their vast troves of knowledge, and if I remember correctly, Nightroar first emerged in a rural village, so it's very unlikely either necromancer could've learned the techniques in a book, and if they do experiment, it'd be very unlikely that they'd conduct the same sort of experiments we would, especially with their apparent lack of scruples involving dead bodies- Nightroar, at the very least, would probably have found it more difficult to purchase sufficient materials for a good golem than to rob a grave.
Of course, we should always be prepared, but I sincerely doubt that Monk would do something like that. Right, Monk? Right? ...Monk?
Ninja'd: Draigh hasn't said anything regarding our experimental aspirations most of us haven't thought or said before, but they were definitely things that needed to be said again. Still, speculation doesn't hurt.
As for the whole human city thing (town actually; I think 'city' is probably overdoing it from what I remember Monk saying), well, I'd prefer to leave as soon as possible, yes, but only because that means we can fulfill our promise to tell Omo about our powers that much sooner, and our haste to leave probably won't be too suspicious to Omo (we could act nervous about the Council coming after us, or excited about seeing new things, or both- although it certainly doesn't have to be an act to work for us) and maybe help mitigate Omo's anger about not telling him sooner if it looks like we were trying to make it so that we could tell him as soon as possible.
We could easily explain why we didn't tell him before, too- we couldn't tell him in either elf-town or human-town because there was too high a chance of being overheard, and even out in the elf-wilderness one surprise attack Ranger patrol and both of us would probably be dead, since they'd probably assume Omo is our accomplice or an exceptionally well-preserved zombie or something. (We could tell him that we weren't sure how he'd react or not, either, but I'll leave that choice up to everyone else- it is, after all, a rather ugly truth, the idea that we didn't trust him enough to tell him this sooner.) It'll make us look paranoid, but who wouldn't be, in our shoes?
In any case, we should definitely
go into town and stay overnight as long as Omo thinks the Council won't come after us, or otherwise will take long enough to mobilize that we can afford it. If he thinks they will come after us and quickly, we should keep moving- though in hindsight he doesn't seem to be very worried about that. (Maybe the Rangers, unsure of what to do about people trying to leave rather than trying to get in, have to ask the Council for orders first? That should take a few days just to get the message there and back, and the Council will probably argue about what to do for a few days as well. Definitely need to
ask Omo about what the Rangers will do about us.)
In any case, either way, we should
grab some essentials as soon as possible- a more accurate map, like others have said, will be of paramount importance, even if it's only the local areas, and some other navigational equipment may or may not be in order- I'd definitely be more comfortable if we had a compass of some sort. I still think we should get a sling, but I suppose that's optional. We may also want to check and see if there are any more spellbooks in the local shops, though there's no telling if we'll find any more useful than the one we have now. Some historical books might be useful, though I doubt we'll find anything particularly revolutionary in a town like Larathor. More crystals might be good, too, though we shouldn't sell any potions until we get to the big cities- that's where the wealthier clients, who will pay more for our services, will be.
Oh, and definitely some information gathering a la Draigh's suggestions in the quote just above the TL; DR would be in order- I'll add to that list asking people about Nightroar's activities, since figuring out where Nightroar is heading (and avoiding his route like the plague) should definitely be one of our top priorities, and asking people where he's attacked before, among other things, will help with that and finding out Nightroar's current capabilities; y'know, beyond zombiespamming.
And no, no hiding. No one really suggested we hide, at least not in the manner you're implying. At worst, they suggested we stay in the wilderness so that the Rangers won't come find us (if they come after us). Besides, just because we enter a town and leave quickly doesn't mean we're hiding, or acting... er, questionable, in any way. The townspeople won't mob-lynch us for being travelers that want to go on to the next city as soon as possible. Now, if we were to hang around all shady and suspicious-like... possibly. But we won't really have a reason to act that way after we get past (a) the danger of the Council catching us and dragging us inch-by-inch back to Elfland and (b) telling Omo about us being a necromancer. Cautious, we should be. Shady, we should be not.
whoohoo, the story continues!
My vote:
We are not in the wilderness yet (one hour walk from a village or city is NOT wilderness), just out of the elven forests. Get a nice sleep at the inn to celebrate our freedom and dry up from our swim.
Also: gather information at said inn about current state of affairs, local mages, general thoughts about magic in Thrimesdur and get the opinions of these humans about elves. That way we know what to expect for the future.
Finally: Check book for basic illusion spells that can alter ones appearance. If they do not like elves, we might want to work on an illusion and pose as humans.
TL; DR: The other necromancers don't seem like the experimenting type, and it's always a bad idea to give the protagonist's powers to someone else in any case. Draigh is right about the whole experiments debate; we should put that on hold until we get more information about the basics, at least. We should go into Larathor, stay overnight, and collect supplies (a better map, a compass, and possibly more crystals, spellbooks/history books, and/or a sling, in order of importance) in the morning. Gather some information as Draigh said before plus whatever we can find out about Nightroar while shopping and for a little time afterwards, then when we've milked the town dry of gossip, leave so we can finally tell Omo and get the whole thing over with.
EDIT: Heehee... "Draigh's list" ^gigglesnort^
Why yes, I am, in fact, quite easily amused. How could you tell? X3
