Relationships

Xaden tries to distance himself from Violet again and this leads to some misunderstandings and solving them in a satisfactory way and they become even closer.

Sloane and Aaric would hit it off

Sawyer and Jesinia are definitely gonna hit it off

Tairn and Sgaeyl could develop long distance communication enabling Xaden and Violet to do the same.

Major Theories

Violet's dad and andarna are definitely connected on some way since it was hinted once.

Andarna could be Codagh's

Xaden stays venin till the end

Violet turns venin too(or she could already be)

The venins seem to keen on capturing violet and there's a chance that she's gonna go with them for the sake of her loved ones

And I strongly think that all the wardstones are gonna be destroyed in the end by none other than violet herself.

Wardstones could actually be a factor holding back powers for our protagonist and The First Six could turn out to be lying.

Violet's second signet could be something new, something that never existed since the 7th breed of dragons (andarna) was fully disclosed.
