I know this is old but I just finished reading the dialogue of the cutscenes after you beat Phoenix and I'm not sure what Louisoix meant at the end, the exchange was this;

Alisaie: Thank you... for everything... Pray take your rest, Grandfather... You deserve it.

Louisoix: There are records of an art that allowed one to summon the power of a primal from the essence of its demise.

Louisoix: And though I am no true primal, all that I have left, I give to you.

"bla bla bla and fades"

Does this means that he gave the remaining of his power to the twins and now, if they research said "art" they can have Phoenix-like powers? Or Louisoix-like powers? Am I reading too much into this and it's more like a "I'll always be with you" sentimental yada yada type of thing?

Sorry if this has been discussed before around here but I don't frequent the forums too much and as I said, I just found out about this.
