Theory: Naga planned for Grima to return to the Past

[Nightmare_Shinigami]

Everyone who played Fire Emblem knows, that Lucina and the other Children traveled to the Past thanks to Nagas Help in order to Change the Future and Grima followed... but what if Naga LET Grima go trough the Timeportal as well?

- If there is no Way back to the Future it means that the Risen had lost their Leader and the remaining Humans could have a Chance to fight back.

- Grima had to turn back to the Avatar's Body, which causes the current Avatar to have a Vision of a Future Event

- Because of this Vision (and the Help of Basilio) the Avatar was able to trick Validar and Grima has to resurrect his Past Self himself.

- Only Grima can kill himself, but since the Avatar (who also Counts as Grima) is still around, their will be able to kill Grima once and for all.

This make sense because I don't think Naga would have let Grima go to the past without a plan to destroy him once and for all.

Definitely plausible. I mean if she could open the portal she could sure as hell close it and I doubt she would have let Grima go if she didn't think there was a way to destroy him permanently in doing so.

This is most definitely a possible event, but I think a lot of people seem to miss key components about Naga. Naga is not a god, and that is something you most likely may know. Although we also do know that the Divine Dragon tribe(which Naga, Tiki and Nowi belong to) was considered one of, if not the strongest tribe of dragons. Keep in mind that Naga has not been one identity throughout the series of games in this world. This is revealed in the Future Past DLC, as Grima had somehow killed Naga and Tiki took her place. Also keep in mind that the name Naga isn't really a name in the way as an individual's identity. In fact any divine dragon who takes on the role of the tribe leader, they would be considered Naga. This includes the males of the tribe. So that further proves the point that Naga is not ALL powerful. In the end she is still just a dragon.

When Naga sends all the children back in time she uses the Outrealm Gate to do so. We know that the gate is not only accessible to her as the gen 1 characters may use it without the help of Naga. Although the origins of the gate are unknown, it is likely that it was created by dragons as they are a powerful and very intelligent race. Think back to Rekka no Ken where after the Scouring the dragons fled to the Dread Isle and created the Dragon's Gate, which for the most part has the same function. The gate was most likely created before Marth's time if it was created by the dragons. This would make sense as just like in Rekka no Ken the humans of Marth's world came from Jugdral or now known as Valm and started taking over the continent of Akaneia. The dragon tribes didn't particularly like this and most started to hate humanity. The dragons at this time also didn't have their human forms as they didn't need them. Now as the rise of humanity happened this world something started to happen to the dragons and they lost both powerful and fertility if they didn't take the form of humans and keep their power in these stones we call dragonstones. Since this conveniently started as humanities rise started the dragons probably hated them even more. In the end the dragons did concede and did to change. All the tribes except the Earth Dragon tribe followed this, only their leader Medeus accepted this fate. So since the dragons were in decline and the humans were taking over, not to mention they hated the humans, they most likely decided to use the gate as a means of transportation to a place where they could live in peace. Or maybe to go back in time and stop the decline of their race and that probably lead them to the cure they found of basically becoming human in a way.

Alright so now that we got all of that out of the way we can finally talk about Grima himself. We know that Grima is most likely a dragon descended of earth dragons. It is also speculated that when the earth dragons were fused together, including Medeus, they created Grima. Grima is extremely powerful. His power matches if not exceeds Naga's. In fact he is so powerful that literally the only way to actually kill him is if he is killed by himself. It is even stated in game that he is an almost god-like being. Now who's to say he isn't similar to Naga when Naga is worshiped as a god herself, when the Plegians worship him like one as well. When in fact neither of them are gods. Although they are both almost as powerful as one. Since Grima is a dragon and if the Outrealm Gate really was created by dragons (and if Naga can use it), then why can't Grima? We know Grima is at least 1,000 years old since that is how long ago the first exalt of Ylisse defeated him. So that means he must have at least some knowledge of the gate. Again Grima is as powerful as Naga, so that goes to asking the question: if Naga can use the gate for time travel, why can't Grima? Grima can even resurrect the dead, hence the risen. He pretty much destroyed everything in the future world and even managed to kill Naga in one realm. He should obviously be able to control the gate if Naga can. And if Grima is the fused version of all earth dragons that could explain it because the earth dragons were almost as strong as the divine dragons, that also could explain why he wants to destroy everything as well.

Well I actually spent a good 4 or 5 hours researching into this last night. I happened to come across this post, and I thought that I should say something. I apologize that it's kinda long but there's a lot of details to be understood. Most of it is still mystery as well since we know so little of Grima. I hope I didn't bore you too much though. I really like your theory as well! I hope you have a great day!

While possibly true, its odd then that Grima doesnt take more advantage of this as he could yank more reinforcements from time and space as he can easily dominate risen. More importantly methinks the dark lord of Dragons may not be able to either use the gate, or use it very well since his botched entry actually made it possible for Grima to get his sorry hide wasted permanetly.
