Spoiler:

Eh? Did you happen to respond to "Yunashia" in my previous post?
Seems so since I don't see anyone implicated such a thing.
It is just a joke to refer to the new Guard of the Spring.

Although I still think the staff gave hints about Aaeru and Neviril's mortality,
I agree to the idea the ending is open to various interpretation and it was their intention.
Truly, their minds and considerations seem much more complex than ours.
