You're expelled onto burned alien planet, and vanilla Overworld may look like a heaven in comparison. Ash, Lava pools, green sky, Acid rains. You're surprised to find water here. The only thing that reminds you of overworld is Botania portal to trade some basic items to get you started. Your goal is to get back home. Check out Exoria, questing modpack from creator of Age of Engineering. Authors description: Mods are heavily tuned to make them work for the plot. What do you think?
This has already been suggested as our next Patron pack. I've been running through it single player style since its release and I can safely say it should start as a smaller community pack, but should be able to bloom into a public one, much like Crash Landing. If we provided each player with a island template with its own limited water and lava supply it should be feasible to leave the rest of the dimensions as farmworlds. So tell us what you think, that's my vision of where this one goes, but it hasn't gone past the suggestion stage at this point.
