Just A Various Reason is a modpack based on mods learning with magic mods (botania or bloodmagic) or tech mods (ender io, thermal expension, rf tools).
To be able to discover them, a series of quest is availableat your disposal (Coming soon), but if you do not want to do quests, do not accept the first quest.
There is no pre-generated world, but there are some mods that allow to have a custom generation. The purpose ofthis modpack is to have an open 
minecraft survival experience with all types of mods, very common mods but also less known mods without going into excess and keep some fps.

This modpack is in development at the moment so it may be realy unstable
