Your ImpactFlux server, with the useful bits included.
Host your ImpactFlux server
ImpactFlux is available for Minecraft server hosting with CreeperHost.
The Github Project was transferred to me after Vanityset and the owner stopped developing it.
The plot:
Steve wakes up in a world, that is so familiar but just a bit different. Before he can get his bearings, a meteor crashes down upon the world. Something.. something just is not right. Another meteor crashes. Run Steve run! Find a way to protect the world from the cataclysm.. the impact flux.
Future Plans:
Add quests to Twilight Forest - potentially tie into Weathering the Storm in a version 2.
Add more quests to Weathering the Storm - make more Roguelike dungeon quests.
Turn down Hunger Overhaul and turn the limit stacks off.
Remove hunger diminishing returns on food.
Add Mariculture quest line?
Add Chisel quest line?
Open to suggestions.

Got questions? 
Yes. CreeperHost modpack pages link into ordering with the selected pack ready to install. You can also change versions or pick another supported pack later from CreeperPanel.
CreeperPanel is built around real modded servers, including update paths that aim to preserve user configuration changes where supported instead of treating every update like a fresh install.
Eco can work for lighter packs, but Premium is the recommended CreeperHost range for modded Minecraft. Premium gives stronger hardware, Turbo Start, Bonus Memory, and Ask Theo where enabled.
