If Cecilia is the weapon prepared by agrona to destroy indrath. Does this mean grey is possibly the weapon that has been long waited by djin to take revenge and destroy indrath and agrona?

Dude. She knew, she even made sure if indrath know about grey being still alive through indrath's servant she deliberately met in destroyed elf country. She even said if this servant might have to choose side. Not between agrona or indrath but to take side to other one that has the possibility to even stronger than agrona and indrath, yes grey.

What about if for all this time. Seris is actually on some degree has something to do with djin's past civilitation and she has been doing all of this on behalf of djin (spy?) in order to prepare particular individual (grey) to take revenge on agrona and indra?
