at the end of saga, the divine visitor deactivates the heresy program. it rushes away to someplace deeper within the sestren taking edge and lagi with it. later we see gash waiting at the meeting place for edge to return, but edge does not return. however we hear a dragon’s wings which could be none other than lagi’s. finally we see azel heading out on her search for edge.
we hear this recording in orta:
[quote=“heresy program”](( Your mission is completed.
Yet, you still wish to remain? ))
(( Your body is fragile and mortal now. ))
(( Your life will more than
likely end out there if you continue. ))
(( Alright, I understand. ))
(( Farewell, my other half… ))
(( I must rest… ))
(( Watch over our friends for me… ))[/quote]
from what we know, this must have occured at some point right after we see the heresy, edge, and lagi rush away in the sestren. if the heresy shut down after the DV did whatever it did, those were the final moments of the heresy that we did not get to see in saga. and shortly after, lagi re-enters the physical world and flies over gash. you following me so far?
so my point is: lagi was going somewhere at the end of saga, the heresy had given him one directive, “watch over our friends for me”, and azel was embarking on her inevitably fruitless search.
my dream was a panzer dragoon between saga and orta where lagi found azel in the electrical storms that anjou had warned her about. her coolia died and she was near death herself. lagi took her from that place and it kind of took on a PDO feel where lagi served as chaperone to the rider. to ease her sorrow lagi humored azel on any desire and takes her all across the region (perhaps to new lands).
and after fighting a suitably gigantic boss, she enters the sestren and creates orta 
but that was just my dream, what do you guys think of the prospect of lagi meeting with azel after the events of saga? it kind of casts lagi in the light of being the loyal family pet, which strengthens the bond between it and orta.
and what do you think of the idea of the devs ever going back in time (again) for a hypothetical PD game? i know i’d love to see the story of the sky rider- leading right up to his death infront of kyle. or the idea i listed above with azel and lagi?
edit- forgot to ask: what do you think of the use of the word “friends” in “watch over our friends for me”. if what i say is correct, azel is the only one we know of that the heresy would consider a “friend”. does this hint at further unknown adventures?
please enlighten me!
Personally, I’d like to believe that it was the Heresy dragon who narrated the English version of Panzer Dragoon Orta because we really didn’t learn about its original purpose and why it chose to destroy the Towers. It was possibly a rogue Tower guardian or the Sestren AI’s replacement or was actually intended to destroy the Towers all along for whatever reason (perhaps because the ancients were human themselves and they didn’t want their own creations turning on them), but for one reason or another shut down the Towers before their task was finished. The fact that it’s keeping an eye of on events sheds more light on its character.
