Q: Does everyone have some sort of system, even if it’s not the same?
A: In this world, there is a sort of system in a broad sense. As Captain Lloyd mentioned earlier, if one wants to advance in their aura they must be bestowed a blessing by the Goddess Iram. This only really applies to those who do not possess mana or supernatural powers. Of course, it is a very vague system to those in this world and is not fully understood. Iram is a goddess that will bless those who put in the effort, but there are tiers for everything including auras. Mages and priests have their own system in this world as well, but that will be discussed later.
Q: Are there any glitches that he’s going to exploit in the future?
This narrative has been unlawfully taken from Royal Road. If you see it on Amazon, please report it.
A: There aren't any glitches per se in this world, but there are things that Ray can exploit using his past knowledge of the game. These include specific items, powers, and ways to impress people. Using this knowledge to his advantage will be essential.
Q: Are there any TV shows/ movies he could exploit?
A: Sadly there is none, Ray was just a normal person in the real world. The only distinct difference was his high aptitude for strategy games and was a professional chess player when he was younger.
Q: Did the game have any crossovers or references to other games he could utilize?
A: Crossovers no, Echoes of Revelo was a standalone game with nothing else added to it. As such, there are no other games or references that can be used. It is its own standalone world without any pollution. There are, however, easter eggs and nods to influential media in EoR.
