Jantus has a hook hand.
By way of Word of God in a chat with a reader, it was confirmed that his Strife Specibus was Hookkind. In the Hivefled anniversary picture, his left hand is obstructed from view, in addition to being a seadweller, this has led this troper to believe her actually has a hook for a hand. Tsukey is going to end up being very important to the plot, somehow.
Call it favoritism on my part if you will, but I just get the impression that, regardless of being dead, her part of the story is nowhere near done.
