Athervox has somewhat mixed feelings about the recent change in government. Certainly, it is to her advantage that House Thrune has fallen; it saves her the considerable trouble it would've taken to properly extract her vengeance from that rather large family of powerful sorcerers, one of whom had, in fact, been the mortal leader of one of the more powerful nations in the world, which incidentally happened to the be the nation whose borders extended around Athervox's own lair. Since one does not grow to become a Great Wyrm by taking serious risks, her plotting had been slow and calculated... too slow, as it turns out, since with the change in government, she had lost her chance. This may mean that she won't need to risk herself in a dangerous and tedious campaign to retrieve her stolen property... but with what seems to be a cabal of archmages now in charge of the country, she knows better than to be optimistic about the chances that they'll just politely hand over the books that were stolen from her.
Accordingly, she had spent much of the last year considering how best to approach the new government with her demands... a task which had at first been hindered by the somewhat confusing stance of said government as to what its plans were, and the general failure of agents of said government to appoint a replacement for the presumably-dead Mayor of Senara, who hadn't been seen since the Four-Day War (and good riddance). But when one of her usual Dominated agents reports on the announcement of a "constitutional convention"... well, that's obviously an opportunity worth investigating! With the right move, she ought to be able to both gather intelligence as to the disposition of the new government and it's intentions regarding her own stolen property. Indeed, she might potentially even insert one or more of her own minions into the newly-forming power structure!
Apparently, there were three sorts of person invited to participate in the convention; pre-existing 'nobility', the chosen agents of various gods, some large number of people chosen "randomly" by a magical spell... and one person "elected" from the population of each of a long list of settlements and regions. Perhaps unsurprisingly, Senara is large enough to make it onto that list... but the local tieflings seem to consider the thing an obvious trap, and what political hints she is able to extract from her minions suggest that the main political factions in town are attempting to elect each other, under the assumption that this will neatly clear the board for their own takeover. Well, she can certainly work with that! All that's needed is to insert an agent of her own into the process... and after some consideration, Athervox finds that she doesn't particularly like the idea of attempting to maintain a Dominate on a representative sent to attend an event sponsored by a cabal of archmages. Even if no one notices and Dispels the effect, there was no telling how long the thing might go on for, and figuring out how to reapply the Dominate was tricky without knowing exactly what precautions would be taken. No, this situation calls for the use of a more valuable piece... one which would retain its loyalty to her even without an ongoing magical effect...
