This is actually my TL3 pitch as discussed with @steffire3, and my antagonist would be an extreme enviromentalist. :D
I was thinking something more along the lines of a
"total conversion" mod for TL2, that reworks the vanilla dungeons, environments, and sidequests (which are currently somewhat boring).
I would put
@Kva3imoda-style machinery in every major magical landmark, siphoning off excess magic. Quests like
"One Man's Trash", would be altered to reflect this change.
There would be a resurgence of
clockwork automata, taking the place of organic merchants (with an accompanying increase in prices, because they
are "bots"). Of course, that leaves most of the honest craftsmen out of business, leading to an increase in the population of desperate highwaymen.
You would have
"toxic waste dumps", where the condensed Nether energy (i.e. "Ember Blight") from "Ember refineries" gets dropped off (near
Netherrealm portals, obviously), full of twisted ecology and strange geology.
You would have
caged dragons and elementals, their life-force drained for some of the more "exotic" fuels. There would probably be
Blight-powered superweapons, and Ember-powered vehicles.
Professional Alchemists formulating designer fuels, with equally professional Engineers as their customers. Advanced
Ember-Tech medicine providing ultra-expensive "cures", while automated
vending machines dispense the more "traditional" potions.
And then, of course, there will always be the nutcases who try to tinker with the
Clockwork Core itself.
Given all this craziness around you, the Dark Alchemist's (relatively restrained) attack on the Guardians becomes a whole lot less "urgent".
EDIT: A possible name for this proposed mod would be "Ember and Tongs".
