all spoilers Theory about the final cosmere

[MIKIL]

so i have this crazy theory about how the cosmere will progress and what the plot will be by the chronologically end book(mistborn era 4). By this time people from elantris, roshar, scardial and nalthis will be cosmere aware and worldhopping will be common. I believe rosharans and nalthis and elantrians are gonna use cognitive realm often for worldhopping while scadrians will be the first with space shuttle. And I believe that the main plot of mistborn era 4 will be of the interstellar, inter realmatic conflict between scadrian side and rosharan alliance with elatrians being a powerful neutral party. That means either harmony becomes discord, or odium actually wins or merges with other shards (odium winning is more probable) Also let me show u what i assume to be the technological and magic level of the major players by the time they meet each other (space era).

Scardial- mistborn and full fueruchemist will be non existent( a myth), and the power level of existing mistlings will be very low. however  by the space era the medallions will be available to all essentially making everyone a small mistborn, or a misting, and hermulialogy will be more widely used.
Roshar- In rhythm of war the honorspren tells about how they were nearly 2000 windrunners before recreance, Assuming that the spren have recovered from the recreance by then and humans and listeners have made peace, we will have a large army of surgebinders, along with a larger army of regals and shardbearers. Also the fabrial technology will advance though not as much as scardians. Bear in mind rosharans and scardians( atleast the northern ones) discovered air travel around the same time.

Elantris- After scardial and roshar the most important planet must be elantrains. They I believe have one of the most destructive powers (2^nd surgebinders) and have already overcame the problem of location. The invested people will be numerically small but will be threatening enough.

Aluminum will become a major player. so will noghtblood and so will be anti investiture. 

I Assume that odium (+honor and cultivation maybe) lead army along with the assumed support of autonomy and other shards and maybe even nalthis( considering their history) fight against the technologically advanced scardians( whom I assume by then have created a space colony and have support of various small planets) and their alliants (hoid, and other shards) . Elantrians and rest of the shards will be staying as neutral party for the most fight. Most probably (or maybe join the scardrians.) I believe that dawnshards will come to play a large role in this war. Assuming survival is a dwanshard  both the parties have one dawnshard each and there will be a race to find the rest 2.what we saw in sequal to sixth of dusk is a result of these race or even geeting colonies for war between this two blocks.

One of the main theories about the cosmere final was the fight against the anti andolosium who created the weapon to destroy him. However it is clear from dawnshard that there was most probably no anti andoloniusm.. and since this was orginally rayse plan and now taravangian said he is gonna save them all most probably by being the sole shard I believe the fi8 will be between todium and others.

Brandon said Era 4 will be more about a mashup of cultures, and SequelOTD would indicate a Cold War. So I think it will be a Roshar/Scadrial conflict, but I’m not sure it’ll be an explicit war.

Just a quick note, Brandon has said that Era 2 is as weak as the dilution of Metalborn powers will get.
