With the looming threats of Zeref and the Dragon Gods dispelled,

lets just pretend they and any other canonical institutions like the Spriggan 20 don't exist

such as Earth for Canyons, Ice for Tundras, Death and Poison for Deserts, Fire and Earth for Volcanic Mountains, Air and Light for Flying Islands, Metal and Animation for Machia Factories

not sure what animation is supposed to be as an element. lightning? also I'd drop earth from volcano since its in canyon. nitpick, I know. I guess you should also include a "Plant for Jungles" or "Lightning for Badlands" too, but again, nitpicks, only the Machia Factory part is the actual integral piece of information besides "there are many environnments" here lol

This also means that Magicians of the corresponding Elements will find their powers increased by a significant amount within a corresponding area,

this could make for interesting writefags I suppose, anons don't make use of environments enough

These creatures can range from something that would "only" make for an S-Class mission back in the Mundane World,

I think it should be clarified that plenty of fodder creatures exist as well, but again, nitpick

Dragons, Gods, Dragon Gods

I suppose Devils should be added as well for consistency's sake
Maybe include Dragon Devils, God Devils (Nephilim?), and a super rare Dragon God Devil which is basically by default a final boss?

Giants are savage and nomadic humanoids that can grow to the size of mountains,

unironically, too big. also a nitpick but "mountains" are really fucking huge, and if they were typical "skyscraper/palace/castle" size it would be easier to use them

Sea Creatures
Secrets

no issues

Origins

no issue with the balancing
could specify the flavor of these 'origins'
like prisoners or criminals are related to a penal colony-esque organization
maybe we could come up with a few of those? specific presences within the new continent, and encourage anons to make their own
idk I just played a lot of Civ 6 recently so it sounds fun to me

Magical Source/Capacity

honestly? I'm not that big of a fan. I feel like the cyoa by itself is fine, this just feels like a needless headache
especially since people will just make a custom that's just opposing magics reskinned so the Shoto Todorokis and Elixirs can have their fun
I feel like 'rebalancing' magic power so everyone is closer in like and not as spread out is a bigger and more important issue, like removing the magic power rankings all together so you can just pick whatever and have perks worry free, encouraging fun more
can't say I'm a genius at design, though, so you do you

You may choose from whichever Magical Power Ranking you would like to be in. Average or Strong Mages are in far less danger and can reliably provide support without being detected easily, while High Mages are far easier to detect and serve as the lynchpin of a Guild's combative power.

don't kid yourself, we all know how this goes
just seems like a bad idea as opposed to just scrapping it entirely imo

as most people will be part of the International Guild: Novus Mundus.

I wonder how much we should push this? on one hand, there will be people recruited just for that
on the other, obviously there will be cliques within it formed of previous guild members who only join it for their guild
might just be better to clarify it as an International Guild Union, where member Guilds either form into it for the period of time of the expedition or some just send groups of powerful members for their interests
not sure if thats what is already supposed to be going on

The Dark Guilds will have to choose between ships that either sail Sea or Air, as Dark Guilds cannot or will not pool together the resources afford the monumental task of making a vehicle capable of being on the land of the Great Unknown.

rip molemen bros
this doesn't really matter much to me but I also don't think it makes much sense? they could just make a shitty dangerous one

the gamier parts (Start: to Embarking)

well... ehhhhhh?? I mean, do those really need to be there?
also, the obvious thing a guild would invest in is teleportation magic
so either there should be a blurb explaining why mass teleportation magic isn't feasible or just include 'teleportation stations', would also make it easier for anons to write fun continent adventures

anyway it would be cool to write maybe a beastiary or come up with faction ideas
I hope the MP pans out
