I need to play these trails games.
The Internet is not providing me enough info of the ones we did not receive.
I need back stories!
You need spoilers? I am right here.
Trails series is a spin off of a spin off.
Legend of Heroes is a sub series that came out of Dragon Slayers series, and then Trail of Sky is really the Legend of Heroes 6.
Trail of Zero is LoH 7. They no longer use LoH title after that.
Sky 1-3 is the Gospel Project plot arc of Orpheus Final Project. Concerning the "Space" Septentrion.
1-2 is the main story. 3 handled the after math as well as setting up a lot of stuff for Zero/Ao and Sen (Cold Steel).
Ao/Zero is the "Phantom" portion of the Phantasmal Flame Project plot ark of Orpehus Final Project, dealing with the "Phantom" Septentrion, as well as the political dispute in Cross Bell state.
Sen (Cold Steel) 1-3 (3 is in development) deals with the Erebonia Empire Civil War and the "Flame" portion of Phantasmal Flame Project, which occurred at the same time with the events in Zero/Ao, thus making them tightly connected.
Civil War concluded in Sen 2, but the dispute in Cross Bell is still on going, as well as Phantasmal Flame Project.
I must add, the plot writing in Trails series is very infuriating in that the writer love to use the same truck againa and again. It is also worse than Xenosaga in the "I'll open alot of plot thread and throw difficult words at you but explain nothing" department.
It is almost a decade now, and we STILL don't have a proper explanation on Phantasmal Flame Project.
Serious, when ever the Apostles are going "Our plan worked!", the players are like "I don't get it, what happened!?"
