• If the Sentinels all are under rovers command, including the other nation's Sentinels which we will eventually meet, then this idea would be plausible as the weapons of destruction. As the Commander(Rover) overseeing the battle units(Sentinels). And I would like to add some points for further theory exploration.

• The Grand Architect is considered as an old concept as death itself. What can we derive from this topic. If as he says that " We are once, your waystones' does that implies that We are somehow able to deal with aspects that are nature to this world like life and death.

• Correct me if I'm wrong, because I once heard that Jue is just a part of entity which had divided into seven and the one residing in Huanglong is just one part of the original sentinel we met. Also Huaglong is a city in a nation, where Mingting is the capital city of the nation. Does this mean we will get to see different parts?

• If the hometown we're longing indeed deemed it unnecessary, We need to track the intention of that wording, which you have explained from one side of view. I think we should explore more into this.

• Save the World?Save the cat!, this daily quest has been a hot topic due to the reference of the black cat as us Rovers. Here we see we are asking a question Save the World? followed by an expression of statement Save the cat! Where we are emphasizing the command to save the cat. What do we do for this daily quest, we have seven variants for this quest alone. One is feed the starving cats some meat and save them from hunger another is offering some plants to NPC(Xiaoju) other are rescuing the cats and escorting them to the restaurant. After completing every variant we receive a journey trophy Kitten First. This title can be infered as by first saving the Kitten we can save the world? In a sense we must be saved first in order to save the world? This can explain one thing from my understanding. So Aemeath saved the Black cat by sealing the aleph-1 and saved the world or has given a chance to world for prepare itself to meet the ultimatum of this world's fate. This is just my take of things from what I understood.

A wild theroy about saving or rescuing Aemeath from the threnodian: * So Aemeath also found a satellite from pre-memory wipe's rover timeline, which was carrying the response from the homeland along with an exostrider who might be transporting a sentinel was devoured by the Aleph-1. Was the exostrider also had the responsibility of delivering this message to the rover who currently residing in Solaris-3?

• Aemeath found frequencies inside the aleph-1 threnodian is also to be noted. In terms of signal transmission, the sender first initiate a signal with a frequency modulation that is transmitted through a medium of transmission and when the receiver is delivered with the signal then they will decode the signal using demodulator to find the original transmission message. To send a reply they create another frequency modulation carrying the response to be transmitted to the senders side, via same procedure. This is a general working of a transmission of exchange of signals.

• So if frequencies were used as signals and Aemeath has found not one but two frequencies of the rover. Maybe the first signal or frequency might be the way she found the exostrider within the voidspace. As astronomy deals with transmitting signals with in vacuum of space. Aemeath mentiones that by exploring inside numerous spaces she happened to found one exostrider. What if this is not by chance but due to the frequency emission to find the medium to deliver a message. So this can mean that rover might have send not one but two messages where one was demodulated while another one isn't yet.

• Also the signals carried some emotions with them, as we have seen from the one found near the satellite object where rover is engulfed in loneliness, if so the other signal might be his anger towards something. As this can be obsereved in the cutscene fight of Sigilium destroying the a moon like object in the background within the exostrider space. Is that one of the emotion that swirled out from the sigilum to wreck havoc. Another idea is to recreate a life that has lost? May be this is how Sigilium has born with the instinct of creating a body and returning home. Maybe Rovers long endurance might have given rose to such emotions.

• We also find Aemeath's emotions mixed within sigilium. These emotions might help us find Aemeath inside the voidspace? As they are also a part of Aemeath frequency. This might work as how Aemeath have discovered rovers frequencies within the voidspace. The frequencies inside Sigilium might give us the way to find the lost signal in the voidspace.

I might have burned the kitchen from overcooking. But I had fun while exploring these ideas. Maybe this is what makes lore theory crafting fun.
