Agree! Large parts of Emer stand risk of being subjugated by the Alliance. Vajaar has already fallen and are now preparing an invasion of Kaitaine (now an official enemy of the Alliance), this at least in my version of Shadow World. I hope that Emer IV will shed some more light on this.
In my version of things, the Ahrereth is actually probably the most prepared and organized against the threat of the Alliance advancement. The Loremasters are sitting on their asses, not even knowing if the Alliance is a bad thing or not. However, the Ahenreth sees the advancement of the Alliance to their doorstep as a significant risk. Jenkyna, is one of only a handful of people (Andraax being another) actually knowing the Thalan heritage of the Alliance. She has not revealed this to any other members of the Ahrenreth, at least not yet, but she sees the Ahrenreth as a potential tool to be used to capture the Thalan (maybe for study, or maybe for more sinister purposes). Kyrunak, the mystic adherent, has quickly infiltrated his way close to the brotherhood...
