Well, not just cost. There were a number of advantages (didn't rely on the strength of the wielder, didn't tire someone out as much to use over and over, much quicker to train someone to use) but the biggest is simply that they're much deadlier, especially against armor. As far as I'm aware, Warhammer actually demonstrates this with the Empire, with handguns being armor-piercing and bows... not.
Of course, once you get into magical elf-bows with enchanted offbrand-mythril arrows and whatnot, the calculus changes.
Actually no, early guns
didn't armor pierce well at all. Keep in mind a bullet was a soft round-ish lead ball which, if its not going fast enough tended to 'splash' against steel plate armor, and this remains true without steel jacketed or high caliber rounds even today. Granted, with enough velocity you're still hitting the target hard enough to make their head ring through a helmet.
By contrast arrows have a hardened steel point which, when launched with basically your entire upper body musculature, is hitting armor with maybe twice or thrice the impact force of a spear, concentrated into a smaller point.
Well made armor would prevent it from getting a straight hit, but you need a lot more metal to stop an arrow than a bullet.
So why guns? Well, training someone to be that swole is a lot harder than getting 2-3 more average dudes with a gun, most opponents
aren't armored significantly, and you have more problems individually with hitting the target than killing it.
So bows are superior for an army when you have a lot of swole and extremely accurate guys, guns are superior when you have a lot of average guys, and they're about par when you're working with a body of swole but not particularly accurate guys.
Which neatly breaks down to:
-Elves - Swole, extremely accurate. Bows, hands down.
-Hunters/Woodsmen - Swole, somewhat accurate due to lifelong practice with the bow as their primary livelihood. Bows, advantage.
-Farmer Levy - Swole, but not accurate at all. About par.
-Urban Levy - Neither swole nor accurate. Guns, hands down.
If I'm following what you're saying, it's that the Elves will think the Ulricans massacred the villagers, the Empire thinks the Elves disappeared them and the truth is the villagers just fucked off to get out of the situation, led by the Wolves.
My objection to this is that unless the Ar-Ulric has sent his men to go burn down and destroy the empty villages after the fact (and no Elves came across any empty villages between the evacuation and the destruction) then there's no way anyone seeing the villages will think they were attacked. Even cutting down running peasants leaves marks. So the Elves must be assuming the villagers are being relocated at least in some fashion, so why would they care where they're going to such an extent it would undermine the whole alliance/conversion thing?
So long as they don't have to officially take notice of the fact the peasants weren't killed, they probably don't care, I think. They're not Dawi.
That said, having to officially take notice could cause undesirable political implications, so maybe be real cautious about revealing that information anyway.
Easiest way to untangle this knot might be for the peasants in question to be able to offer the Elgi some form of recompense, 'cause I'm pretty sure the Elgi aren't actually worse about grudges than the Dawi, and even the dwarves have ways to end things before violence happens. Under the circumstances, we might be able to wrangle some of the credit for helping with the Waystone Network be counted as recompense on the part of the Nordlander peasantry.
That... probably requires higher skill in diplomacy, though.
The crux is that the elves want them gone. They don't care how.
They're gone and the forest is reclaiming the villages, no reason to check further.
However, it'd be a breach of alliance when you tell them you'd "get rid" of the settlers and then instead evacuated them.
That said theres nothing distinguishing the Ulrikadrin former Nordlanders unless you were personally familiar with them. Even if Eonir walked in front of one they wouldn't know, Nordlanders are everywhere, why would they think theres any connection to the lost villagers?
The solution is to let their origins be forgotten.
As it happens, they live a half day march away from Eight Peaks, theres basically no reason for the Eonir to ever encounter them.
Well look at it from their perspective... Humans are on and individual level worse at everything than members of the elder races (barring heroes) and their two claims to fame as far as I can see are inventing necromancy and being the favored servants of the Dark Gods.
I figure the human perk is that they got nothing, so they're willing to try everything.
Most of the time it ends up with the person trying hurt, humiliated or dead, but sometimes you can get a true gem out of it.
No. People keep making this mistake. The elves predate the Winds of Magic. The elves were built to manipulate whatever pre-magic energies that the Old Ones made available though the geomantic web.
Probably resembled High Magic a lot in nature if so. Braiding High Magic out of the Winds is putting Humpty Dumpty back together again.
