In Resurgence, you have awoken from a long sleep. While you dreamed, the world around you was changed drastically. On the surface, you can not find a single living thing during the day, while at night, undead and worse, attack relentlessly. Underground, not a single ore can be found, except in perhaps, the most dangerous of places.
While discovering clues about what happened to your world, you must build a thriving infrastructure of technology and magic in order to repopulate your world and bring it to life once more.
Hundreds of quests will help lead you upon the way, though you are free to choose your own path as well.
Many recipes have changed from what you recall them to be. If something is not working the way you thought it would, perhaps some research or a little experimentation may be in order.
HUGE credit to thephoenixlodge who created the original "Regrowth" for creating an incredible modpack that provides countless hours of fun, as well as the inspiration and drive to create Resurgence. Be sure to check it out!
